I wish to have more options in TACC to choose larger distances to car in front. The currently largest setting is 7, which gives between 2 and 3 seconds' leeway. While this may well be more than enough for Tesla's reaction time, it's much too close for driver to relax and for front end of Tesla to avoid dirt, sand and rock shots. It is particularly terrible in semi-crowded highway traffic at normal speeds in the spring where there is no point in overtaking, but winter's mud and sand is still on the road. As it is now, I can't see any reason for using or even having any one of the levels 1-6 at all. I hope that a simple software upgrade will make it possible to set the level in seconds instead of a random number. 1-7 seconds' options would be perfect. Please vote up if you agree. I suppose Tesla is monitoring these forums.
