For safety purposes. You need to have lots of space during high speed driving for you to have the time to avoid the car in front of you in case there is a sudden brakes or unwanted commotion in front of you and also to have a better view of what's ahead.
At highway speeds, YES!
It will take about about 1.5 hours at highway speeds.
About an hour at highway speeds.
When you're cruising along at highway speeds on level roads.
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.
My 1999 Trooper gets about 16 MPG with mixed highway and city driving. I believe that it has the same drive train as the 2001. If I drive at moderate speeds on the highway, I can get 19 MPG.
This can only be done in theory and not in practice, but it should take about six months to travel to the moon at highway speeds nonstop.
a patched tire can be safe to drive on for short periods of time, but shouldn't be driven at highway speeds as they aren't as safe
You can't even drive a scooter on a highway. If you are trying to get somewhere, you must take slower back roads because most mopeds can only reach speeds of about 50mph.
It depends on how fast you drive and whether you stop or not along the way, but at highway speeds with no stops other than quick ones for refueling, around 12 hours.
It varies from one make to another but in general a drive cycle consists of starting up cold, warm up while driving at normal speeds around town and also a short trip at highway speeds then shutting down allowing vehicle to cool down. That would be one drive cycle.
