Yes, Laws vary here, especially from state-to-state, it’s not consistent through state statutes.
It would have to be proven without a doubt that you were distracted manipulating a smart phone or touchscreen interface while driving if an accident was caused due to your own negligence with inattentive driving.
Common sense will never prevail for some people, but like I said before, if someone has a problem being distracted from a touchscreen or anything in that nature, then leave the controls alone until you’re safely parked. It’s a really basic concept, but it’s a massive problem here in North America that results in a lot of vehicle accidents, which totally could be avoided.
Physical controls are much easier to toggle without taking your eyes off the road through repeated motor function, but it’s one of the transitions that manufacturers are moving away from, because it’s a ‘cleaner, aesthetic look’. Tesla would be an example of that.
