There's a difference between driving fast and being ready to move when an opportunity appears. It mainly comes down to watching traffic far enough down the road so you anticipate where the gap will be. That then allows you to smoothly merge into it.

It’s so dangerous when the passenger tries to pressure the driver to go. If they thought it was safe they would have gone. If they decide to listen to the passenger instead of their own judgement, they are way more likely to get into an accident. Even if the advice itself is good they might take too long to process it or misunderstand. Like “Take a right, now!” then they drive up onto the curb ten feet before the turn.

Also, if the driver is making mistakes out of nervousness, yelling at them makes it worse every time. My passenger yells anything they can walk the rest of the way.

Only the worst drivers never miss the turn.

There's a nice little app on F-Droid called Speedr.

Edit: Not seeing it there anymore, but found the github for it: https://github.com/jakehilborn/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.

Edit: Also, not sure that math adds up. Going off of my memory from a few years ago.

This how I be shouting at other drivers lol

If you hesitate, wait.

Everybody just wants to get where they're going safely. If you're always behind slow drivers you need to leave a little earlier because if your schedule is that tight any little thing is going to make you late.

Most people die between 40-60.

Speeding isn't dangerous. The ability to make smart decisions about when to speed is.

This is why I just let my wife drive. She'll run the light at the last second if she can while I never will, and it's less frustrating for both of us to just let her handle it.

Self driving cars will be so much fun if they become the norm
