Butthurt? No, I'm just laughing at the fact you managed to wipe out going in a straight line. The only thing embarrassing is when all the import kids buy cheap mustangs and start wrecking left and right, turning the mustang into a meme car.
That still doesn't make it a great idea to be driving with a coolant leak.
Like I mentioned above . . . the amount of help that TC and AdvanceTrak can provide is still limited. I tend to doubt that the car suddenly decided to "snap loose" at 66°F unless you were clowning around/showing off and maybe hit a damp spot/loose sand/other tire grip killer.
I mean, knock on wood, but I don't have any issues with my GT/PP. Granted, winters here are mild but I drove all winter on the stock P-Zero tires and didn't go sideways once.
I made the mistake of installing new takeoff summer P-Zeros from a Mustang GT PP on my 2013 Mustang GT. So easy to break the P-Zeros loose when cold and if not careful you could easily spin the back end around so I wouldn't let other people drive it. I did drive 70 miles in snow with 1600ft elevation change in the summer P-Zero without any issues but I was very easy on the gas. Passed 4 accidents that day.
You'd think in the course of a year he would have learned how to handle rwd.... I guess it is a good idea he goes back to a car with training wheels.
I am sideways on purpose, not by accident as I turn off traction control for the fun factor. Winters here are mild with an average daytime temp of 50 in the Winter months but nighttime temps go into the 30/40's and until the sun comes up the roads are cold. Add in cold tires right out of the garage and you have a skating rink until the air and tires warm up. My center display always shows tire pressure so I know when the tires are warmed up.
