There’s a nice little app on F-Droid called Speedr.
It checks your speed against what open street map has set as the speed limit for the road. It will record how often, how long, how much you drove over the speed limit during your drive.
It will then use that data to estimate the amount of time you actually saved.
I regularly drive ~15 mph over the speed limit to keep up with traffic. Do a long drive of more than eight hours at a time around every other month. In a year I saved under 20 minutes.
Maybe a more aggressive driver could get more savings, but as far as I’m concerned I’ll just leave a little earlier.
Assuming a “long drive” is at least 200 miles and most of the trip is on a highway without a lot of slow spots, you should save much more than 20 minutes a year regularly going 15 mph over.
With a lower highway speed limit of 60 mph, going 15 over will put you at 75 mph. In an hour, you’re 15 miles further down the road going 75 than 60 and it will take you 15 more minutes going 60 to get to that same spot.
Specific conditions will change the numbers, obviously. I’d consider both a few hundred mile drive and driving through NYC during rush hour to be long drives and they’ll have vastly different stats. By all means leave earlier but that Speedr app seems like it’s mathing wrong.

That math ain’t mathing.

I tried to find the app but couldn’t. Are you sure it’s the right name ?
