It’s nothing to do with the car and everything to do with being a halfwit, I reckon
We live in a modern cul de sac which is at a fair gradient. Observation today indicates that FWD cars get up with no/minimal spin whereas RWD ones are stuffed. There is a 90 degree corner at the bottom which means that there is no way anyone can hit the hill at over 3 or 4 mph without risking a sideways drift into some bollards, so gently has to do it.
I have driven proper 4×4’s in the desert, in the snow, and been on various off road training courses. I can get the Cmax up no problem and no spinning. My BMW is parked out of harms way round the corner at the bottom of the hill as there is no way it can be driven up.
however if you wanna come round and prove me wrong I’ll stick the kettle on 😛
