Can only say everything has its limit, even with cars with ABS is just safer but there is a limit on what the ABS can do as well. Still bores down to using better brakes, and tyres.
I usually don't go for 2nd hand tyre unless it is really still that good condition which I saw one 95% thread left but age of tyre not stated. Michelin PP2 which was discontinued. So thought of replacing with that if the age of the tyre is not old and really good condition then can consider.
Well, such drivers they only can hope that the other car would not fly over bumps, is just normal reaction that they will fly over bumps just to overtake cars that they intend to overtake
But then wish them good luck on their suspension and engine mountings
