I think the failsafe is to not allow anything beside voice calls if it detects movement. Phones while on motion are a convenience, not a need. Before the 90s very few people had mobile phones and they got places fine.
That is absolutely false. I didn't even own a car in the 2000s because going anywhere meant a bunch of printed maps, bad GPS, and getting lost. Google Maps liberated me to a whole world of restaurants, side trips, urgent plan changes, and last-minute tourism. Plus podcasts, voice memos, and time sensitive texts. It kills me that safetyism is throwing out all those babies with the bathwater.
That’s on you. Like almost everyone over the age of 50, I learnt to drive before mobile phones and GPS, and it was fine. Paper maps and street directories worked well enough. Getting lost was uncommon, and no big deal.
