Is the real question What car for driving over other stuck cars ?
2wd with snow tires is good on iced roads esp as typically they weigh alot less than 4x4s but come unstuck due to ground clearance ime
4x4s( unless your talking about faux by faux cars) really need to take it easy in the twistys and under breaking due to the weight and high cog
Key to remember is youll move forward easier in 4×4 but its still the same two wheels doing the steering the same 4 doing the braking as youndo in a 2wd car.
And finally , if you dont know how tomuse a 4×4 properly it can just make it more difficult to be rescued, you need to undersand their limitations.
