Once I was chatting to my neighbor. Among other things, she mentioned, that when she attended defensive driving course, they were teaching about proper distance between cars at a stoplight. They taught to stop so, that you can fully see rear wheels of the car in front of you.
The reasoning under this was, that if your car gets hit in the back, it does not hit the car in front of it at that distance. Well, this does not sound very true for me. I have at least two problems with this approach. First, it is not uniform. Imagine, what distance you should keep if you drive, say, Silverado. And now imagine you drive Honda Civic. I would think we are talking about times, not percentage difference here.
Second, it is excessive. Even with Civic we are talking about something like 10 feet, if you sit properly. Did you say the bigger the better? There is a downside to the bigger – long line at the stoplight. Sometimes it does not matter, but pretty often it does, especially for turn lanes and for intersections like this:
This intersection I’m passing every day. Route 123, which is going west - east, is a major road here, and when stoplight at the arrow 1 turns green to let the pictured cars cross the major road, stoplight at the arrow 2 turns red. It allows only the cars, which are in between the lights, to cross the road. During rush hour one can spend 5 to 10 minutes here, waiting through several stoplight cycles.
Following this rule on such an intersection is a disaster to other drivers. And most of the drivers do understand, that by stopping at the big distance, they are wasting the space that could have been used by fellow drivers behind them to save a couple of minutes (duration of stoplight cycle) on the way home.
One should Learn these courses that tackle everyday driving problems by imparting training on:
Emergency care
Principles of Safety
Fleet Safety
On-Site Emergency Response Planning
Safety Communication and Training Techniques
and Roadway work courses on Flagging
Agreed, you have to use common sense, in heavy traffic going slow speeds you can bunch up a bit. The old rule about "if you can see the bottom of the tires of the vehicle ahead" worked when cars had high, long hoods. These days vehicles are very aerodynamic with sloped hoods and windshields that provide excellent visibility. Following this old rule can put you right on the bumper of the vehicle in front of you in most cases.
At a minimum you should leave enough space to see a bit of pavement between you and the car in front. Could someone comfortably walk between your two vehicles?
Here's a new rule of thumb that will help. Imagine that the vehicle stopped in front of you was to break down and you had to go around...are you far enough back to accomplish this without reversing and with enough confidence to enter the next lane of traffic fairly quickly?
.
True, it won't necessarily keep you from being pushed into the vehicle in front but it will prevent crowding/upsetting other drivers and minimize damage if you're rear-ended.
I've taken quite a few driving and defensive driving courses and have managed to avoid many accidents in my 25 years of driving (10 yrs professionally) by applying different skills I've learned. Hopefully my expirience helps you as well.
Hi Misha
I though you explained your point very well and wasn't really trying to re-visit your points but was just focusing on one aspect. I think the balancing all the considerations, risk assesment, consideration for others, traffic, intersection layout (which you covered very thoroughly), and basic guidlines of what you should try to achieve all go towards being a good driver.
Thanks for taking the time to chat, happy motoring!

Yes and no Trevor I think. Cause I am maintaining that people usually leave too big of a distance when they stop at the traffic light, and you are basically saying they need to leave even bigger distance.
May be it is that driving habits where you live are seriously different from where I live?
Saving couple of mins can be critical in busy lanes but the picture in the lane
suggests traffic free lane. Hence its preferable to stay behind stop line.

If you have enough distance in front of you that are able to weave out and move to another lane... you are being rude to everyone behind you. Move up a bit. There should be enough space that an imaginary couple holding hands could walk between you and the car in front... but no more space than that.
People who hog up buffer space in front of them are very rude to those behind them who are trying to possibly get into the turn lane, but cannot reach it due to buffer-space hogs in front of them.
I cannot stand when someone leaves a big gap at a atop light especially when they are chatting on the phone! It will take them up to 10 seconds before the move once it turns green! The stops signs only blink 14 times so you only have appr. 15 seconds to move through it. I do leave a space in between vehicles but not a large open space so that others will get peeved! You have very valid points and this rules makes completel sense.

That's exactly why I wrote this post Julianna! You girls are cheering me up a lot, cause after all those years I was already starting to think that I am alone or almost alone with sensible and reasonable approach to driving LOL.
