I agree with being measured and predictable; I take advanced driving and safety class every couple of years as a refresher and safety is a massive priority for me. And I'm a big fan of cruise control. But going fast in the fast lane IS measured and predictable :-)

As well, 20%, or say a difference between going 10km over vs 10km under on a 5hr trip, is an hour and that's not nothing :-/

Being predictable is the best way to avoid an accident.

Amen. This is why I use my turn signal when changing lanes every. single. time. Over 20 years and counting without an accident.

Be glad you don't live in Texas, where using your turn signal is tantamount to issuing a challenge, and is seen as aggressive behavior: "Oh, you want that right lane? No, it's MINE!"

Or worse, people don't see turn signals enough to know what they mean, and just adds to the confusion.

I am a Texan. Always use the turn signal.

Is this an (accidental?) +1 for robo-cars?
