Firstly I'm glad passengers were OK, that is the important thing.

The 911 cannot be blamed for the crash, I have driven all iterations of 911 at high speed in the rain over the last 25 years way before any electronics were around to assist (or not) the 911 is no better/worse than any other car in the wet, it is ALL about the tyres.
The cup type tyres have to be respected in the wet that means under 100kph/60mph IMO and even slower in standing water or else you WILL aquaplane.

With well treaded Michelin PSS tyres, 200mph is perfectly in control in wet conditions

In that case doesn't matter what car or tyres, you will aquaplane and probably crash if going over 40mph

I too am glad the occupants are ok. That's a horrible accident.
That being said, I think it's ridiculous to blame electronics or even the tires for this situation.
The law of physics apply here, aquaplaning is very difficult to control at those speeds. Any driver that thinks otherwise is foolish.

Are we talking about 930s or 997s?
Agree w the hydroplane comments.
Generally, if Psm is kicking in, you're doing something wrong, again generally.

I've routinely done 80-85mph (129-137kph) in the heavy rain with nice quiet Bridgestone Potenzas without any hydroplaning. Something like a Toyo R888 might be a whole other ballgame. I'd look at the tires for the principal blame. Those sorry Michelin Pilot Sport tires truly SUCK. Loud, hydroplane-prone, they really SUCK, and I'll never drive those LOUD tires again. Sorry you had your wreck, glad you and your wife came out ok. As to faulting you for your driving abilities, I'm not that sort of a douche. I've done much crazier things with my turbo and came out unscathed. The thrill of the "edge" as you say is quite addicting.

I used to own a 996TT and generally found the PSM to work predictably except on one occasion on a sharp ramp on cool tires at aggressive speeds. Car went unexpectedly sideways while coasting, which I caught and then basically drifted through the curve while the PSM just went along for the ride and never intervened! There are documented cases of the ABS failing on these cars and any PSM computer is only as good and reliable as it's sensors.

1+ on the Bridgestone Potenzas. It's the first time I've had them and so far so good.

Funny, I would take the PS2's or PSS's over Potenza 040 or 050 in a heartbeat. The 040's back in the day were just dangerous in the rain, the 050's only a bit better.
PSS is a bit noisy though, compared to PS2 or PS3 IMHO.

Very happy with the 050A in the rain.

Glad you guys are OK. As for the crash, you have had a wrong tire set up for that particular stage. I would not recommend use of semi-slicks on wet ever, especially on the roads with water puddles. Not enough groves to channel the water away, let alone the fact that standard width road tires will go into aquaplaning as soon as you hit the puddle of water, even if the speed was just 80 mph. Once tire is off the ground, there is no stability system in the world to control it.
