Back to my own experience. Today I used LeafSpy Pro to disable the automatic locking. I'd forgotten how unpleasant it is to have the car lock you in as you drive away, and then make you unlock the doors yourself if you park but leave it "running." I disabled that right away in my 2013, and while there is no info on doing it with the lock button on the 2018, I suspect that if you play with holding it down, it may be possible that way as well.
I also found (in the manual) how to use the auto high beam function, although I have yet to try it. That will be handy, if it works well enough. I don't think I've mentioned it, but while the high beams on the 2018 aren't the best I've ever experienced, they are much, much better than the Gen I high beams! The low beams, though, are a little worse They remind me of the aftermarket LED beams on my Vectrix maxi-scooter: very bright, but the low beam band is too narrow, and a bit too low.
