Dear Dr. Gridlock:

Reference: the letter from William Scheiderich about parking problems at the New Carrollton Metro station [Dr. Gridlock, June 23].

If Mr. Scheiderich doesn't mind driving to RFK Stadium and getting on the Metro at Stadium/Armory, he will find it much easier to park in the privately owned lot near the stadium. It costs $5 for all-day parking, and there is always plenty of space. The Blue and Orange lines go to Stadium/Armory.

My husband and I have given up trying to park at New Carrollton whenever we go into the District on the Metro. There is always a hassle.

Thanks for the tip. As I mentioned before, the parking facilities at Landover (Orange Line) and Largo Town Center (Blue Line) do not fill up, Metro said.

Car Care 101

Dear Dr. Gridlock:

A car's life span depends on how the vehicle is used or abused. The oil will keep the engine clean, but frequent short trips will overload the oil's detergents with water, acids and other byproducts of combustion.

A poorly tuned engine might dilute the oil with unburned fuel. On longer drives, the oil gets hot enough to evaporate some of that.

Hard engine use when the oil is cold will cause increased wear. The interval between oil changes should be adjusted to the vehicle's usage, and generally when the oil looks really dirty, it's time for a change.

Manufacturers' recommendations are based on worst-case driving.

Thanks for the tips.

Bagging Free Parking

Dear Dr. Gridlock:

On 25th Street NW in the District recently, around 6 p.m., I watched a man park in a metered spot, place a plastic bag over the meter and proceed into a building. He was in the building for at least 15 minutes.

I had many thoughts about how he was trying to trick parking enforcement. Then I wondered whether he was a food delivery person and this was an acceptable means of identifying himself to any potential ticket writers. Do you have any insight?

I've never heard of this, and neither has Bill Rice, spokesman for the District Department of Transportation, which has jurisdiction over parking meters. Does anyone else have any thoughts?

Ticketing the Police

Dear Dr. Gridlock:

Gallery Place during the evening rush hour seems to be the new congregating corner for police, who park anywhere they like, any time they like. We recently saw four of them park in front of Legal Sea Foods, a location that you and I would be towed from, and go over to Chipotle.

I have seen police motorcycles parked on the sidewalk in front of Starbucks.

I regularly see Metro Transit Police cars parked at bus stops, D.C. police parked in front of fire hydrants, and police from the U.S. Mint parked alongside clearly marked yellow curbs.

I think people might be less enraged about parking enforcement if police throughout the city made at least a minimal attempt to comply with the laws we all have to follow.

I challenge anyone in charge to visit either Gallery Place or Capitol Hill any evening at rush hour. They'll see police equipment blocking traffic.

Police officers responding to a crime park where they can. But when not responding to a call or while off duty, they are supposed to obey traffic regulations. That's what they say, anyway.

Let's try this: You write them up. Get the car or scooter number and send it to me along with the date, time, address and details of improper parking. I will ask police to investigate.

Laggards Not Tolerated

Dear Dr. Gridlock:

I have no problem stopping for a school bus that is discharging or loading kids; it is the law.

I do, however, have a problem with the kids. On my way to work, I have had to stop for a school bus, and the kids just take their sweet time walking to the bus.

On most occasions in the morning when they are loading the buses, the kids just saunter toward the bus as if they have all the time in the world, not caring about the drivers they are delaying. After a few minutes of this insanity, I find the car horn on the steering wheel! Enough is enough.

I think the school system should educate kids to be more considerate of those they are inconveniencing. After all, assuming that a motorist doesn't run them over out of anger, they will one day be behind the wheel of a car on their way to work.

If a stopped school bus is using its flashing red lights, motorists have to stop. If the bus is slowing, flashing yellow lights signal caution. I'm not sure what the status of the bus is when you are encountering the described loafers.

I would say generally that you should respect their loading and unloading process, even if it seems slow to you, and the students, of course, should be mindful of traffic needs.

If this is a constant problem, another route might make sense.

A Lesson From Paris

Dear Dr. Gridlock:

I recently had the good fortune to spend a week in Paris and used its Metro frequently. Their solution to seating near the doors seemed quite intelligent.

There were eight hinged seats near the doors that were used when the car was not crowded. Then, when a large group entered, the people on those hinged seats stood up, making room for the other passengers.

When it became less crowded, they sat back down. It worked well and provided flexibility within the cars.

Spokeswoman Lisa Farbstein said Metro considered the Paris model but decided not to use it. Seems like it might have been useful here.

Relief in Sight

Dear Dr. Gridlock:

What is going on with the never-ending construction on North Capitol Street north of Michigan Avenue? Will it ever be over? The multiple unpredictable lane changes are really confusing and are not well marked in advance.

Allan Glass

Bethesda

The project should be completed by the end of the summer.

The city began the 18-month reconstruction of North Capitol Street, from Michigan Avenue to Harewood Road NE, in December 2003. It is on schedule, District Department of Transportation spokesman Bill Rice said.

The project includes resurfacing; new sidewalks, curbs, gutters and streetlights; and the reconstruction of two bridges.

Eating on Metro

Dear Dr. Gridlock:

Wow! People are so afraid that they fear speaking to eaters on the subway [Dr. Gridlock, June 23]! When I see Metro riders eating or drinking and I am near them, I always tell them that is forbidden.

Most are tourists who immediately put the food away. No one has ever told me to mind my own business or has gotten nasty. Quite the opposite: They thank me.

I always mention the incident of the young girl who got arrested for eating french fries a few years ago.

In defense of innocent eaters, Metro does very little in providing large signs for all to see easily. On the ends of the trains there's a small sign advising what is not allowed. Metro should place larger signs throughout the trains if it is really serious about this rule.
