I could and do shave about 45 minutes off of the timing you set up. If you're renting a car, how about just joining the expedited service club (e.g., Hertz #1 Gold) for free so you just go straight to your car and drive off? These days, I check in for my flights before leaving home as well. And I aim to be at the gate 30 minutes prior to departure.
Turns out, I'd now be saving 1:15 by flying. Considering that driving is four hours, and flying is two hours and 45 minutes, you'd have to work pretty hard to convince me to drive it.
When I was living in Houston, I actually chose to drive once to Austin instead of flying, based on that very argument. Even for that one, as close as the two cities are, driving ended up taking sufficiently longer than flying that I never bothered doing that again. SAT-AUS, sure. But that'd pretty much be it for me.
