Wiper spray buttons to squirt coffee into mouth as well.

And the hazard lights to automatically minimize all open windows

or hazard lights for linter warnings.

I did for a moment considered jacking the car up, putting monitor on the bonnet, connecting to OBD and using pedals and steering wheel for simracing controls.

Then discovered steering wheel angle and break/clutch is not available on OBD bus in my car.

I like it. Memory is the highway and you use an indicator to show that you are entering a critical section.

The steering wheel could invoke :earlier xs (when rotated by x to the left) and :later xs (to the right). We'd have a time machine.

Emacs users are sometimes stereotyped as wanting foot pedals to get more of those sweet, sweet control and meta keys.

Quadruple buckies that require actually hitting one of the keys with your nose are fun.

Damn, I'm guilty of that too

And if driving a classic vehicle with a manual choke, engaging the choke tells you about vim commands

I want the blinker lever to manage normal/insert mode.

BMWs don't come with blinkers - never seen one being used.

I had to laugh the other day when I did indeed see a BMW indicating, but they were going round a roundabout and using them incorrectly....

There are persistent rumors in the greater Munich area, that there are actual people being payed by BMW to, gasp, install them. But these are just rumors and horror stories we tell our children if they don't eat their vegetables... I think...

Nah, just boss nephew's cousin needed a job.

Don’t forget to change the blinker fluid every 9999 characters typed.

BMW driver here: what’s a blinker? I’ve never changed the fluid.

No turn signal!
