Teslas Adaptive Cruise dead last? I don't think there is another system on the market that I would even trust to slow for other cars appropriately. Is this thread for real? I don't think I understand the issue? Do you all have some TACC system from some parallel universe? 6 months ago everyone was bitching about having only regular cruise control available unless they paid for autopilot.
I guess I have never used Cruise Control anywhere except on the freeway. Is this a thing lots of people do?
There certainly IS another system on the market that you can trust with its adaptive cruise. I drove one of those for 7 years, on the freeway, on rural roads, and (where it really earned its keep) on some very curvy mountain roads of NC. In all that time it never applied braking except when it needed to (except approaching curves, stoplights, signs, etc). Its forward collision alarm never went off except when hard braking was needed (like Tesla, it couldn't/wouldn't apply very hard braking - that was up to the driver). If I had to complain about it, it would be its slow acceleration after a slowdown. So, it CAN be done. In 3 other adaptive cruise systems I tested recently, none of them except Chrysler could track a car on a mountain road. I know this because they couldn't track on moderate curves. That Charger I had would go through mountain roads behind another car like it was being towed by it, even when all I could see was1/4 of its rear end. When I bought my Tesla I just knew it would be better than that. I just knew it. Tesla!
But the real issue here is that TACC will often brake pretty hard (0.15Gs to be exact) when there is nothing ahead to warrant a slow down at all. And for me at least, it does it fairly often. I'd say once every 10-20 miles when I'm in traffic, and occasionally when I'm alone on the road. Most of my driving is on rural roads. I don't use it on city streets. On the open freeway with not many cars around it does OK. Just OK, because on occasion it's done it there too.
What I'm hoping for is people with your experience to chime in and say it never or very very seldom occurs. That would tell me that my car needs a sensor adjustment or something. Anything fixable.
