Having autocrossed in the rain, it’s incredibly fun and useful since you constantly lose control of your car even at very slow speeds during the auto-cross. Worst part is having to work in the rain and generally getting massively wet. I assume you’re using a rear wheel drive car too?
I had it happen to me on the normal roads as well and you instinctively learn to counter steer and try to balance/control the car.
Would prefer to just auto-x on wet ground without the rain.
