Dear Dr. Gridlock:

I live on Capitol Hill, work downtown and drive to Lewes, Del., most weekends. Therefore, I am a regular driver on Interstate 395-D.C. 295, and Route 50 in the District and Prince George's and Anne Arundel counties.

I routinely observe reckless motorcycle riders on those highways. I never observe that anywhere else in the region. (I regularly drive in Northern Virginia, Delaware and Montgomery County and have not once seen that driving behavior there.)

Almost every weekend I encounter groups of anywhere from two to 10 motorcyclists driving wildly down the highway (usually on Route 50 between the D.C. line and Annapolis), weaving in and out of traffic, usually at speeds well in excess of 100 mph.

I live two blocks north of the Southeast-Southwest Freeway on Sixth Street SE, and I see and hear these maniacs screaming up and down the freeway day and night. It amazes me that more accidents are not caused by these out-of-control drivers.

Has anyone else reported this situation to you? I can't be the only one who has seen this. Of course I never see the police stopping these motorcyclists (they, literally, probably could not catch them).

It would be a service to the driving public if you would publish this letter and request that the police in the District and Maryland make an attempt to target these drivers in their traffic enforcement efforts.

Patrick G. Startt

Yes, I have received such complaints. The next time you see these kamikaze motorcyclists, dial #77 on your cell phone and report them to the police. Send me the particulars (time, date, direction of travel), and I'll ask law enforcement officers for their thoughts.

Children of the Streets

Dear Dr. Gridlock:

It seems as though schoolchildren do not know what one is supposed to do with a sidewalk. I have noticed for some time that the kids are most likely to be walking in the middle of the street.

I live in New Carrollton and am close to two schools. This morning, when taking my dog to the vet, I encountered as many as 10 kids at a time walking halfway out in the street. I came around a curve and there they were. Had I been traveling at a higher speed, I may have hit one of them.

They look at you as though it is their right to be in the middle of the street, and they just stroll slowly out of the way of the car. As soon as you pass, they spread back into the street. I think it is the responsibility of parents to teach kids safety and not to always blame the motorist.

The police should try patrolling the neighborhoods as kids go to school and give them tickets for walking in the street.

Tips on Tailgaters

Dear Dr. Gridlock:

When a tailgater gets too close I switch on my headlights. The tailgater thinks that I have applied my brakes and backs off.

Jean Noble

Bethesda

Dear Dr. Gridlock:

One trick I've used to get tailgaters to back off is to use my window-washer spray. I've found that in washing my front windshield, a good portion of the spray will fly over the top of my car and onto the windshield of the offending tailgater. They usually then back off.

Certainly nothing illegal, and, besides, you end up with a clean windshield.

Dear Dr. Gridlock:

You requested suggestions on what to do about being tailgated [Dr. Gridlock, Sept. 5].

As you point out, braking hard is lunacy, but changing lanes carries its own hazards.

My solution is to slow down very gradually until the tailgater has had enough and decides to change lanes, thus taking on the risk of that maneuver himself (it's nearly always a male). Then, I resume normal speed.

Don Juran

Rockville

Dear Dr. Gridlock:

Your snippet on tailgating on the interstate suggests that it is the tailgater who is in the wrong. More often than not, the slow people in the left lane are at fault.

Left lanes are for passing, not for camping out and cruising. It's a rule of driving that seems to have been lost on American drivers.

A.J. Foreit

Arlington

I thank you for all your suggestions for dealing with tailgaters. They include slowing and forcing the tailgater to pass, turning on headlights (thus faking brake lights) and turning on windshield wipers to toss wayward droplets at the tailgater.

I believe a tailgater demonstrates that he cares little about his safety and yours. Therefore, I still suggest you put on your right turn signal and move right as soon as possible. You want this maniac out of your life immediately.

Using the other tricks suggested above prolongs the confrontation and risks escalating it.

Blinking at Signals

Dear Dr. Gridlock:

I read with interest your column on how to get another driver to turn off their turn signal when it has apparently been left on by mistake [Dr. Gridlock, Aug. 15]. Most people mentioned that they get in front of the other vehicle and give some sort of signal.

I was wondering how much trouble they went through to get in front of the problem vehicle and how much time they spent watching that vehicle behind them (forgetting about what is in front of them) while waiting for the driver to turn the signal off.

With the traffic problems in this area, such a situation could probably be left alone. Chances are if you notice that the signal is simply left on, drivers around you most likely will, too.

Wyatt Miedema

My original advice was that this situation should be left alone because gesturing or signaling may cause more confusion than benefit and could distract both drivers. All of us have left our blinkers on at one time or another; when we see that situation on the road, we know what it is.

Dear Dr. Gridlock:

If a driver forgets his seat belt, he has chimes and lights to remind him. Why couldn't the same technique be used for turn signals?

If a driver makes a turn and doesn't use the turn signal, a chime could ring and a light flash to remind him. After he's been annoyed enough times, he may remember.

It's simple Pavlovian training, and the technology is readily available.

Messy Metro Cars

Dear Dr. Gridlock:

I've been a daily Metro rider for more than 20 years, and never have I seen Metro cars as filthy inside as I did this summer. That was the case even in the mornings, before there was much time for people to trash the cars.

I was astounded by how much garbage (including copies of The Washington Post's Express newspaper) was strewn throughout the cars and by the amount of dirt literally ground into the carpet.

Many times I have flat-out refused to sit in the last row of seats at the back of the car, even when seats are at a premium, because of the disgusting God-knows-what that previous riders have deposited on and around those seats.

Has Metro fired or cut back on its overnight cleaning crews in an effort to save money or something?

Roberta Jones

Arlington

Dear Dr. Gridlock:

I am responding to Bill Ballantyne's letter and your response in the Sept. 5 Dr. Gridlock column. Mr. Ballantyne complains about food and drink in Metro cars, and your column asks, "Is Metrorail the clean system it once was?"

My concern is that both the original letter and your response miss the point that the restrictions on eating and drinking are fire safety measures, intended to reduce the accumulation of trash around electrical equipment, which produces heat and has in the past ignited drifts of discarded material.

The King's Cross underground disaster in London was traced to several factors, one of which was the accumulation of trash under an escalator.

The smell of smoke in a train halted in a subway is disconcerting, much more so than just the possibility of a stain caused by careless eating.

No Clue on Congestion

Dear Dr. Gridlock:

I commute from the District to Fairfax on either Interstate 66 or Route 50. What governs which route I take is often the message on the overhead signs at the east and west ends of Theodore Roosevelt Bridge.

Often the signs do not reflect current traffic conditions, and I end up stuck in traffic on I-66.

Those signs must have cost several hundred thousand dollars to erect. What good are they if the person writing the message is asleep at the switch? It ends up costing me and hundreds of other busy commuters time, money and aggravation and adds to area pollution.

Seymour I. Hepner M.D.

Washington

I've asked the Virginia Department of Transportation about that and have not heard back. Another reader asked about the usefulness of those signs, and I invited participants of my Monday Online column to tell me their thoughts. Eighty percent of the respondents found those signs, such as "Congestion Ahead, Exit 64," more irksome than helpful. Who has memorized the exit numbers? Wouldn't the name of the road be more helpful? And, how much congestion -- backups for miles, or blocks?

Then you have the no-information-at-all signs, as Dr. Hepner observes.

Help may be ahead: The Federal Highway Administration is testing electronic signs that give the approximate number of minutes to the exits ahead. They are constantly changing, as measured by sensors in the road.

They are being tested in Atlanta and San Antonio. Let us hope they arrive here. We could use the help.

Don't Dial and Drive

Dear Dr. Gridlock:

I am writing in response to a letter in your Sept. 2 column.

Cortney A. Smith of Ashburn wrote of an apparent act of road rage that she experienced.

In her letter, she admits she was using her cell phone at the time but says she still was paying attention. I think that any use of a cell phone while driving prevents one from fully paying attention to driving.

While I agree with Ms. Smith that the driver she encountered acted recklessly, she also was reckless to some extent by using her phone while driving.

Alex Boyko

Leesburg

Dear Dr. Gridlock:

I just read the Cortney Smith letter to your column and your response.

I thank you for your P.S. regarding the danger of driving while holding a cell phone, but I think it could have been worded even more strongly and a stronger admonition could have been given to cell phone users about the effect their driving has.

Having driven behind many cell phone users, I find they often are inattentive to their driving. They slow down, drive erratically, forget to use turn signals and so forth. I think they may be oblivious to the impact of their cell phone use on their driving.
