(They also don't do blending between friction brakes and regen, so the cars behaviour when letting of the accelerator is highly inconsistent depending on temperature and charge level).
One of the reasons I long for the lease on my Model Y to end so I can replace it with a less stupid vehicle.
Many thousands kilometers later I hate it almost as much as at the start, so lack of regen configuration will be a dealbreaker next time I pick a new car.
1. It is inconsistent, especially during winter and when fully charged.
2. Crossings with shrubbery/objects that hides approaching pedestrians/cars/bikes and it is rare that there is anyone actually crossing. I encounter these several times per day.
My preferred way of approaching #2 is to reduce speed well ahead, start gliding and put my foot on the break pedal to be ready for a complete halt in the rare case (once in a 500 maybe) that I need to give way to someone. In the Tesla I must reduce speed to almost standstill and creep slooooowly, since it would take half a second to move the right foot to the break.
I understand it sounds like an extreme corner case, but for me it is all the time every day. Central Scandinavia.
I want my right foot on the break pedal, ready to brake hard and fast in the rare case that something comes across the road.
I don't want to reduce speed any further than is necessary to have a safe breaking distance at fully ready state.
With any other car (that I have driven) than the Tesla, I can approach a situation like this at between 20kmh and 40kmh, depending on the specifics. In the Tesla I need to go at between 5 and 10kmh.
I generally turn off the auto regen braking because i find it uncomfortable.
Importantly, regenerative braking is a danger on icy roads. I disable it entirely in the winter in eastern Canada because it often causes the tires to lose grip.
They didn't care much for convential wisdom and car building competence in the early days of Tesla.
