How I think of it is this (and it may be entirely incorrect):
The synchronous motor here is likely very "coggy" to my understanding and wants to not spin if no power is applied. In order to make it spin, you have to be driving it at a very precise speed (synchronous). You can tell the difference in speed between the two powered wheels and see if one is spinning more than it should (implying slipping because of the open differential) but otherwise it's hard to tell if it's slipping or not. It's not just applying torque, it's basically selecting an exact speed (which I imagine is selected in the context of accelerator input and current speed).
Your not-a-cure-all statement is not incorrect, but:
Fine and reserved throttle control results in 0% power being applied to the front motor unless the rear is slipping, and that rear slippage could have been prevented if the front was already engaged.
- If I have AWD, please let me use both the front and back axle so I, the driver, can utilise all available traction to minimise slippage.
- EVs have instant torque but extremely gentle throttle application (which would be fine in any other vehicle, including older Teslas) shouldn't result in high torque that causes the wheels to slip. The driver isn't asking for high torque with their foot.
To be fair, you've also explained throttle and traction control in ways that doesn't exist in reality which is why people aren't listening. There is no traction control for regen, but you claim there is. You claim backing off the throttle applies front motor power, but it does the opposite. You claim driving at 60mph (and accelerating there as fast as possible) is a sensible way to drive in winter because it gives you more traction. None of these are true, and why you're seeing resistance to your statements.
I have no doubt that the way you are driving is "fun", but I'm looking for safety and confidence instead.
The rear wheels do not need to slip get power to the front wheels. But you might, unavoidably/unintentionally, encourage them to slip in order to get power to the front wheels by unnecessary acceleration. That can very easily happen on slippery roads. If what you said was true you'd have to burn rubber to get the 0-60 AWD numbers cars get from both motors. And you know that's not the case.
This is partly @StealthP3D argument. That he feels you can instantly engage front wheels (as needed) with the prefect feathering of the throttle enough to get power to the front wheels without the rear wheels slipping. That simply is not true all the time, and not easy to do, nor should you even have to think about it. It's a no brainer to get front wheels going on dry. It's even a no brainer on wet. But it's not so easy on snow/ice and behavior does not work.
We want preemptive power going to all wheels, not wait for acceleration of any kind.
