1. Staying with the pack
The classic rule of thumb that the government uses for setting speed limits is that the posted speed should be around the 85th percentile of natural traffic speed. It's often lower than that, though, because a lot of areas go with preset speeds. That means most of the cars are speeding. Translation: if you’re not keeping up with the flow of traffic, you’re presenting a greater risk by going slow.
2. Driving in the right lane
If you’re in bumper-to-bumper traffic, sure, you can be in the left lane, but otherwise, the left lane is for passing only. Not only is staying in the left lane a great way to spark road rage in those around you, but in many states you can get a ticket for obstruction of traffic for staying in the left. Bravo to the officer above for enforcing the rule.
3. Braking with your left foot
Braking with your right foot entails moving your foot off the accelerator, over to the brake, then down. By keeping your left foot near the brake (not on it!), you reduce the time it takes to actually start slowing down in an emergency. Even if you’re only reducing your time by half a second, that’s 50 feet at 70 mph. If you’ve ever just barely rear ended someone because you didn’t stop in time, there’s a good chance that left foot-braking would’ve prevented it.
A note to those reading this that wish to cry foul and say braking with your left foot is dangerous, or that it only belongs on a race track, or that you’re likely to hit both pedals: You’re wrong. Let's just quote the NHTSA here: "both-footed driving does not seem to be a problem for those who have driven with both feet all their lives." Case closed.
