While I never tune while driving, I got rid of the autotuners for the HI-Q 5-160 antenna and installed a switch to allow me to transfer the antenna to a FG-01 analyzer.
Short loaded antennas are, by their nature, pretty narrow band for tuning. When I still ran HF mobile, I found that a rig with an auto-tuner was a big help in extending the useful bandwidth of an antenna. If, for example, the antenna was resonant on 7075, a tuner might match it to the rig from 7000 to 7150 or even higher, whereas without the tuner I'd be limited to about half that.
Bearing in mind that in a mobile installation, coax is too short to introduce enough loss to matter, so it's merely a matter of making the rig's output stage happy (and running at full output).
