This would cause serious engine damage, as the engine speed ( rpm) would be too high, and the engine would overheat badly. The engine parts would be seriously overheated and the engine bearings and seals would probably begin to leak oil from over pressure.
-it would probably burn out your rear seal and blow oil everywhere but other then that it shouldn't be to bad, maybe
Actually, the worst that happened is you used too much fuel. Engine overheating doesn't occur in any particular gear unless there's a problem to begin with. High RPM's for short periods aren't harmful. After all, you increase your engine speed when your car goes into passing gear, there's no harm done to your auto.
It could also overheat your transmission if it is an automatic trans. NOT good. If it is a 3-speed automatic, being in 2nd gear would not be as bad as if it were a 4-speed automatic though. Because then the RPM's would be higher than on a 3-speed, creating even MORE heat.
That will depend on how fast you are driving. About 1 hr 45 minutes at highway speeds.
They "reset" while driving at highway speeds.They "reset" while driving at highway speeds.
It would shorten the life span of the engine some.
Common cars can't do highway speeds (65 mph) in first gear and many have rev limiters.
If by this you mean only "hot heat" when drive at highway speeds likely thermostat bad and/or almost stuck and takes long time warm up from high engine RPM during highway driving.
The distance behind the car you are following
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.
Yes, it helps when driving at highway speeds.
That completely depends on the speed, but at neighborhood road speeds, from 4-8 minutes. At highway speeds, more like 2 minutes.
Yes, if you had to make a sudden move at highway speeds you may lose control.
First the car engine and thus the air conditioning compressor are running faster at highway speeds, so the unit is capable of more cooling. Second highway speeds force more air over the condenser coils which are in the front of the car, which means they are more efficiently cooled by the outside air thus allowing the system to more efficiently cool the inside of your car. You might want to check the "charge" of the system if it gets really cold on the highway, and is less than adequate in the city.
At highway speeds yes, in city driving no.
