Remember the `two-second' rule


July 03, 2005|By Jody K. Vilschick | Jody K. Vilschick,SPECIAL TO THE SUN

I ASKED last week for some unwritten rules to live and drive by as we cruise Maryland's highways and byways. I received quite a few, but my favorite is Andy Weaver's "two-second rule."

"When the rear of the car in front of you passes an identifiable spot along the road, count the seconds until the front of your car passes the same spot. An interval of two seconds provides the necessary reaction time for you to stop should the car in front stop unexpectedly," he said.

He noted that this rule works regardless of your speed.

"It is much easier than keeping so many car lengths of distance between cars," said Weaver, who lives in Linthicum. "Who can tell the difference between two and three car lengths?"

If you made it the five-second rule at higher speeds (55 mph or faster), I'd love your rule.

But wait, there's more.

"A corollary rule is the `Sandwich Rule,'" Weaver said.

This rule indicates that if the car in front of you is following the car in front of him too closely, you should allow another two seconds of interval between cars.

That is a very good unwritten rule to live and drive by. More unwritten rules next week.

Find, share a ride

Get the most from your morning commute and help beat high gas prices by joining a carpool.

By rotating the driving chores on your daily commutes, you can spend time kicking back and catching up on the day's headlines or catching an extra 40 winks. It is almost like hitting the snooze button all the way to the office.

"Ride sharing is an integral part of reducing highway congestion throughout the state," said Neil J. Pedersen, state highway administrator. "A person who travels 40 miles roundtrip to and from work spends an average of $440 a month or $5,280 annually in fuel cost and vehicle depreciation.

That's enough for a fantastic family vacation."

And, if you have to stay late or leave early, you can still get home easily.

The Metropolitan Washington Council of Governments guarantees a ride home in case of an emergency or extended work hours.

For information about sharing rides: 800-204-4828, or the Maryland Transit Administration Web site, www.mta All SHA park-and-ride lots offer free parking, and many operate 24 hours a day, seven days a week.

A number of park-and-ride lots in Anne Arundel still have plenty of spaces available. These include the lots at Route 2 at Route 258, Route 4 at Lower Pindell Road, and Interstate 695 at Hammonds Ferry Road. The park-and-ride lot at Route 4 and Route 408 has only a few spaces regularly open.

Gassed up

Are rising gas prices getting you down? Here are some tips for saving money at the gas pump, courtesy of AAA Mid-Atlantic.

Compare, and remember that prices are lower in areas with many competing outlets. Off-brand gas can often be 10 to 15 cents a gallon cheaper.

Keep tires properly inflated. Underinflated tires cut fuel economy by as much as a penny per pound of pressure below the recommended level.

Easy does it. Accelerate gently, brake gradually, and avoid hard stops. (Good advice even if you're not worried about gas prices.)

Check your tank. Do not purchase midgrade or premium gas unless it is specifically recommended in your owner manual or is needed to prevent knocking in an older vehicle.

Filling up a 12-gallon tank with regular rather than premium will save between $1.50 and $2 a fill-up. Ignore oil company claims in advertising that premium is better for your car's engine.

Keep it slow. Obeying the speed limit saves gas. As you drive faster, aerodynamic drag and rolling resistance increase. As a result, at speeds above 55 mph, fuel economy decreases rapidly.

Keep it together. Combine errands into one trip, or go to one location to take care of as many errands as possible.

And, I would add, trade in your gas-guzzling SUV for one of those cool, fuel-efficient Mini Coopers or hybrid vehicles.
