My other half was driving her Ampera, and I was in the 4+. We arrived at a set of red traffic lights with 2 lanes and the roads were quiet., but damp.
We both went in to sport mode, and when the lights changed off we went at a leasurely pace, obviously not racing.
The 4+ spun its wheels and failed to grip, and backing off and booting it again it did the same thing. The Ampera was faster to the speed limit.
Has anyone else been wondering if their traction control is working? The wheels seemed to spin far to easily in a straight line, and the car clearly struggled to grip.

Clearly a case of “Less is more“

Salt on the roads reduces friction a lot, even when it’s dry. Why use sport mode under these conditions?
Traction control only cuts in after the car detects some slippage. It doesn’t (and can’t) prevent the slippage in the first place.

Not really too tricky to figure out, did that about the second day I had the car... I have not experimented to see if the auto hold makes any difference.

Just logical, it won't fire off the motor if you have the brake on... Pretty sure it also works without sport mode...

Those Primacy 3s slip on wet leaves! Think I'll try the Goodyear Vector 4 seasons next - which unlike the Michelins have 'run flat' capability - anyone got experience of Goodyear on eNiro?
Surely so would any other tyres in that situation? I think a lot of folk are blaming the Primacy tyres just a bit too much. Michelin is one of the worlds best tyre makers IMHO.

This car has buckets of torque when giving it some beans. This will cause wheel slippage on any tyres when on low friction cold, damp and slimy surfaces. Also, it’s a relatively heavy car to accelerate and as the weight distribution is probably less biased towards the front wheels (compared to typical fossil cars).

I reckon the original tyres are probably quite good overall. IMO their worst feature is probably their relatively high cost. Beware of run flat tyres as I believe they tend to be much heavier and less energy efficient (perhaps noisier too??).

To those who advocate running the tyres at increased pressures for efficiency, expect the wheel slip to be perhaps be even more pronounced.

A simpler response to the OP, don't try acceleration tests on wet roads? What's the point, to add the variable of the tire compound and tread, etc.?

Yes I understand you have rain. Applying enough throttle for wheelspin in the wet suggests excessive acceleration for the conditions to me.

You can get a ticket for that here in the USA.
