I absolutely despise tailgaters and have done a lot of experimentation about how to get them off my tail or prevent them
from doing it to begin with. Now that I'm retired and drive a thirsty truck, I know slowing down will help. I use cruise control as much as possible.
But what to set it at? Put it on the speed limit and you'll be tailgated immediately. I usually set mine at 4-6mph over. That shows whoever is behind me I'm not just dogging
it at the speed limit to make some ecological statement (don't you hate that in the left lane?). Most folks are happy to drive at 5 over even if they wanted to do 8 or 10 over, like
I used to. But now I knock at least 5mph off. My Ram hemi is quiet and comfortable at 70.
btw, no brake checking, half the world has a dash cam and anyone who does that to anyone else is risking a catastrophe and letting their emotions get out of hand.
I watch a lot of youtube accident videos, have found them to be helpful in learning new defensive driving techniques.
Newbury, I leave one full car length between me and the car in front at a stop light. Drives some folks behind me nuts, who are already six inches off my bumper.
Well now I have a big chrome tri-ball hitch back there with a nasty looking chromed hook on it for towing. If you want some friend, this is what you'll get...
