Not use their high beams and drive dramatically lower speeds.

A missing lug nut can be quite dangerous for anyone who is driving. This means that the wheel is not as tight as it should be and it can come off especially when one is driving at high speeds.
why is my 1991 Mazda truck surging at higher speeds
Higher g's produced at higher speeds are harder to survive.
It is on because there is a problem with the charging system. Most likely the alternator is defective.
Because your motor is spinning faster at higher speeds causing higher rpm's
They "reset" while driving at highway speeds.They "reset" while driving at highway speeds.
You rotors are warped and will need replaced/resurfaced.
Highway driving tends to be consistently moving forward, whereas city driving is a lot more stop-and-go. Higher speeds are reached on the highway. Highway driving tends to be straight line and long curves, whereas city driving has a lot more turns.
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
You need to replace or clean the ERG valve. This will help with your milage too.
