1) ALWAYS WEAR A SEATBELT. (I got this one right, at least.)
2) If the tyres are a bit low, PUT SOME MORE AIR INTO THEM.
3) If the road is wet, remember that IT TAKES LONGER TO BRAKE.
and most of all
4) Next time, get up twenty minutes earlier and TAKE THE TRAIN INSTEAD.
Thanks, everyone, for your support. Temporary replacement car will arrive this afternoon.
