You are still missing the basic point, Garmin provides every other standard, normal, common, garden variety Nuvi out there with the menu option to disable Restricted Mode. There's nothing special about having this option, it's ubiquitous. Everywhere, almost all of them. Many thousands.

Heaven forbid, Garmin even provided some models such as the GVN53 with a REMOTE CONTROL to operate them in the vehicle, along with the same menu option to turn off what it calls "Safe Mode" while they were enthusiastically waved about.

And newer hybrid devices are also road capable and have vehicle mounting brackets available...but don't have restricted mode at all. For example my 66i, there are many others.

If you are obsessed about passengers unwelcome advances on your private device that's your private business but is of little interest to anyone else here. If you are really concerned about safety then maybe better to redirect the soapbox away from here to Garmin: [Only registered and activated users can see links. ]
