I agree 100%. In the car I run a PAssport 8500(red). Using that plus visual cues has saved my ass over the years. The only time I got in trouble was when I was accelerating hard next to another car accelerating hard. I should have waited because there was a hill but i threw the dice anyways and failed.
There also is a neat toy pepople should look at. The Passport Laser shifter is FTW. It does work against laser, I've been in zuht's old mach1 when he got lasered at high rates (80ish) and he slowed down from the first 3 laser shorts to resonable speeds.
