The real risk is to tend to the screen so much while driving. If you can’t figure things out there instantly, then look at the [expletive] road! There are signs.
And what if you miss a lane? It happens. You’ll survive. Which cannot be said for every accident imaginable with drivers not paying attention to the road.
Edit: Just to be clear … I wasn’t there, I’m not criticising what you personally did or didn’t do, I’m just giving a different general risk assessment for a screen demanding attention.
