So one thing I'm trying to understand pushing the Roadster to its limits and becoming more connected to the road is whether or not to keep TC on or off when pushing the Roadster HARD through the turns. I'm talking really pushing it, where you feel the front becoming light and it really pushes the G's like a insane rollercoaster ride from hell... I've always felt confident in my 1.5 since I think the TC is not as sensitive as the 2.0 I'm driving around now. Although I've felt it kick in when I've pushed my 1.5 before, but not as often, the point is still valid. The issue here is that I feel the TC is really going to take me out one day if I don't make sense of it... meaning that today I pushed the 2.0 very hard through the Santa Cruz Mountains... Traffic was HELL on HWY 17 today so I took HWY 9 and then over a few other twisty back road stretches to get back home. StandStill traffic just feels your just ticking time away with Zero worthwhile experiences... So getting back.... I pushed the 2.0 very hard through a few hard fishhooks and many S... double S and triple S tight turns on my round about journey back home. What I felt was that the TC kicked on as I was diving into many turns... I had NO connection or control of my back wheels... I wanted throttle and thrust from the back.. pure acceleration to get me out of the smooth sharpening turn that was getting ready to open back up... all I got was a dud pedal since TC kicked on. It actually overthrew me more than I expected into the turn but I luckily didn't have the turn sharpen up all that more. I lost all my connection with the road.. No power... No control. I just sat back counting the silent milliseconds counting and was hoping for the best that I'd get my power back... and it did. But time without power can be costly. So I guess I'll need to do this and retest the route / turns pushing just as hard with TC == OFF. Now this will have to use some caution, its all driver and feel at this point... I understand the feel and connection to the Road driving the Roadster, but I do have to be aware that my backend will and can break loose and also understand it WILL throw me into an unforgiving rear end slide and unforgiving break-away if I lax judgement at any moment. However I've pushed my 1.5 hard with the tires down low whipping the back end out with TC == OFF to understand where exactly that limit is and my body/mind has that limit in a sense programmed in as long as I do my part and keep focused. All I can say is that it feels hopeless and powerless when TC cuts your power off completely and its not a good feeling at all.... It would be better to power-limit the TC, possibly another option to still allow some power to the wheels giving the driver more control. But I don't know how the car would handle that physically with the G's. Although it does have an accelerator, there can be some computing and negotiation to do some smart sensing on the TC which I believe the Roadster's don't have. From what I found every Tesla owner who autocrossed turns TC to OFF while racing. So my impression is that it can work against you at times like these. Curious from others what their experience is like with TC on or off and turns as well as any tips from the autocross gang.
