OOI, is there an 'emergency, take it down to (say) 20% option', (user
option, rather than workshop / tech) in case you were out of fuel and
wanted to get somewhere safe?

There's an EV mode button. You can press that and it won't start the engine
when you start driving. Eventually it will when the battery gets low. You
aren't supposed to run it without fuel in - I don't know what happens if it
can't start it. Possibly you can force it to limp a bit further somehow, I
don't know.
