@ascentale @MartyCormack @bikenite A3a: Same way as for any other trip: familiarity and an understanding of speeds.
BUT!
This is another eBike thing. I can do this reliably _because_ if I need to I can turn on / up the assist and _know_ I can go faster if I'm running late.
The ability to go faster for sure is one of the big advantages of _car_, right? You probably won't be nailed for speeding and if you fall behind you can make some or all of it up, or at least feel like you can.
With ebike, I estimate times at 14-15mph, but if I'm late and I need 18, 19 mph, I can get the assist going _even if I'm tired_ and make up the time. It provides _confidence_ of schedule.
You don't need a throttle for this, I don't have one.
