There are so many rocks on the road here, you're begging for a cracked windshield or chipped paint if you stay behind a semi for too long. I've got a chip AND dent in the hood of my Fit just from normal driving, so I won't be hanging out behind semis any time soon.

The onboard computer on the old Daytonas was a really nice feature. I regularly used that on my trips to keep up with the mileage I was getting. That should come on every car, IMHO.
