It isn’t a question of speed (for me). Here is a common scenario. Busy intersection, I’m trying to turn left, I need to hurry so I hit the gas hard (this is a prius so that is not a reckless thing to do)
The traction control senses something like 10% of slip, so to be ‘safe’ it cuts power for a second, completely. Now I am not moving at all. Then power comes back on suddenly, it detects a bit of slip again, power back off. Herk-jerk-herk-jerk
I’m not expecting a prius have a “turn TC off” button like a corvette, that would be asking too much. But they could raise the threshold at which TC engages, and instead of cutting power completely they could reduce it. (maximal tire utilization comes when part of the tread face is slipping anyway)
But because they do not want to get sued they make it super super sensitive…drives me nuts.
Some cars ABS systems have a similar problem, where braking on bumpy surfaces can result in much less braking than you should get. But at least you can steer!
the traction control thing is getting to be a common problem in a lot of new cars these days.
How about driving the appropriate speed for the conditions. That will deliver the best “Traction Control” going? On my snowy day drives into work, I would say 8 out of 10 vehicles that I see in the ditch, are SUV’s and trucks. It’s great that they bought these rugged vehicles, but they need to know that the basic laws of physics apply to all vehicles!
