dear flat tire dennis
that sounds like race driver talk - your advice about driving with flat
indeed - brakes are a tv/movie/radio sound effect taught response -
real accidents rarely have brakes applied and almost always when they are a
real accident is sure to follow -
i have not driven race cars but i have read several professional driving
books and they all detail how brakes are for holding a stopped vehicle on a
hill
also as a former professional class 1 driver - brakes are to be used
sparingly there too-
funny thing i just read today that jack knife is the single cause of rig
incidents on the road -
and i know from training that improperly applied brakes are the biggest
cause of jack knife-
thanks for the reminder to lay off the brakes in emergency situations -
now if only those who brakes when going into a corner could be taught to
simply let their foot off the accelerator in advance of the corner
or simply gear down going in and accelerate out or the corner ...
then my life would be perfect -
yours

There are two kinds of jobs in the world:
Picking up garbage and telling people things.
Successful people do both, with the same good attitude. (riw)
