i have a real experience. it was a day with very heavy rain, and i got onto the freeway to try to get home. as I was speeding up while still in the on-ramp pocket a big rig passed me, splashing me with a shit load of water. suddenly my rear tires started skidding.. (doing a burnout) despite me doing 50mph in 4th gear! and having barely 150hp.
it was funny. try to avoid being near a big truck during heavy rain.. especially behind one.
