you should use your cruise control to save gas
When people drive
on freeways, they tend to speed up and slow down constantly,
even though it may seem that the speed is being held constant.
And it is all these little accelerations and decelerations
that can really add up when it comes to your gas bill.
When you are travelling
on the freeway, you should start using your cruise control
setting more. This will help avoid the slight speeding up
and slowing down cycles that drivers tend to do. You should
also pull out your manual and find out what speed is best
for fuel efficiency in your vehicle, and set your cruise control
to that speed.
