Hazard lights absolutely are driving controls in some countries. I'd argue all countries.

If you must stop suddenly on a motorway, the hazard lights give additional warning to following vehicles. Switch them on as soon as possible. This is especially important in low visibility or at night.

Fans are also essential. You obviously don't live in a climate where the windscreen can fog up unexpectedly.

As I mentioned, hazards are a physical button. I don’t know what the issue is.

For the fans, usually they turn on automatically, but sometimes I have to turn them on by voice control.

As I have said before, these are all things that are trivially easy to handle without removing one’s hands from the wheel or eyes from the road. Some folks are just hellbent on tilting at this windmill for some reason.
