This is such a cop-out. “No computers!”, but it’s okay to let someone drive who isn’t paying attention because they’re deep in their phone? I drive a motorcycle and I’ve had people stare me straight in the eye, only to pull out in front of me and nearly kill me.
People are notoriously bad at driving. The computer doesn’t have to be perfect, just better than the soccer moms or distracted dummies.
Sega Nomad was my favorite, bit I’m not sure you could really classify it as a handheld since it ate through batteries like nobody’s business
