Increase the Maximum Follow Distance

21

Description

In TACC, offer a greater following distance than the maximum of “7”.

Competitive/Pricing/Notes

Here, at least for highway driving, we’re trained to maintain 3 seconds between our car and the car ahead. Whatever “7” means is too little. And with all the gravel they use on the roads to deal with ice and snow, the current TACC follows too close and gets hit by sand/gravel quite a bit.

So, annoyance notwithstanding, if a normal human following a vehicle at less than 2 seconds is unlucky enough to be behind someone that really slams on the brakes ( deer, child, delusional fantasy..), there _WILL_ be a collision. Mostly that doesn't happen, so mostly there aren't collisions, but that is just gambling on luck.

 

So, yes, having TACC option below 2 seconds is infact putting your life in the hands of Autopilot, since that is beyond human reaction time.

Why not use: 1, 2, 3, 4, 5, 7, 9

I despise people using too much space on the roads in good conditions, it creates unnecessary congestion.

BUT when this is not a problem and the roads are muddy or salty, having a longer follow distance than step 7 definitively could be a good thing to save some washer fluid.

Totally need this! In some speeds the maximum distance is not even enough to keep the minimum required distance to the vehicle in front (3 seconds where I live).

Each interval increment is approximately.5 seconds.  A setting of 7 equates to a little over  300 feet at 60 mph which seems like a lot.  However, it takes about 1.5 seconds for the average person to recognize an event ahead, decide how to react and begin to execute their reaction.  This leaves about 2 seconds to stop for example.  The result is a car that takes about 150 feet to stop at 60 barely avoiding a rear end collision.  This supports the ability to opt for greater interval options for more cautious drivers.

It would be nice above 60 mph.
