55 saves lives. I'm not sure that it it does based on accident statistics, and probably the best thing they could do to increase road safety is to remove the truck speed limit in my state, either let everyone go 70mph or everyone go 60mph, but don't intentionally increase interactions between cars and trucks by giving them different speed limits. One thing 55mph does do is help with gas mileage. I drive a hybrid and get around 48 mpg at 55mph and 41 mpg at 70mph. This is a relatively aerodynamic sedan, I'd imagine that the difference is even greater for trucks and big SUV's.

As far as big SUVs go, I drive an '04 Ford Expedition (parents gave it to me years ago when they no longer needed the child transporter and it's stupid easy to keep running). If I drive 55 mph, I get 20 mpg on the highway. If I "drive with the traffic" in CA, I can get as low as 14-15 mpg.

  In my limited experience with LA traffic, "drive with the traffic" means stop-and-go traffic :-) In stop-and-go, I usually get around 52 mpg. Which is why I got the hybrid in the first place, to commute in rush hour traffic, but I bought it just before the pandemic and work-from-home, so never really used it to commute.

    Oh, stop and go traffic is real, real bad for me (10-12 mpg). I was talking about matching speed with the person in front of you on the highway. That number doesn't necessarily correspond with the speed limit. I might have gone to a hybrid or an electric car already if it wasn't for the fact that I lived next to my office and walked to work. Then the pandemic happened and I rarely go anywhere :( Felt real weird having an apartment right next to your office but working from home because it was closed. Ended up just getting rid of it and moving in with my parents because living alone while not being able to see anyone was not doing kind things to my mental state.
