The thing most likely to cause an accident with my car is the horrible Apple Car Play system via USB. I don't know if it's a VW problem, Apple problem, or just a bad combination of the two. It can be so frustrating and fiddly that I'll just pull over to deal with it. I've been considering going old school with a mount and just use the car speakers via bluetooth instead.
VW problem. My missus' VW Polo has the same problems. I did work out that a brand new, known-good cable and working out that pressing and holding the power button to hard-reset the dash would get it to finally start connecting every time (or connect properly after it's done its "I'm useless" failure mode)
CarPlay is hit-or-miss. It's been totally unusable in every Chevy I've driven and moderately bad in some other cars, but it worked flawlessly in my last Chrysler rental car of all things.
You know what's even better than a working CarPlay, the cupholder in my own car that can hold my phone in a nicely visible spot.
Car Play has been reliable for me in a Toyota. Now the Toyota software, twice in two years I've pulled over to power cycle the car because the head unit was wedged. I'm not sure how that compares to other cars but never had to reboot any of the many rentals I've used over the years.
