I had to finally give up on Google Maps in my car because after 15 minutes or so into a route, Google maps would start to lag reality by about 20 seconds. It got very difficult to actually use to drive a route. I thought it was poor GPS signal, my head unit’s slowness with Carplay, etc. Finally I tried Apple Maps out of desperation and it just worked.
As a bonus, it is better at giving useful driving directions. It will say things like “the right at the second stop sign”, which is a great signal to use to a driver.
I do occasionally use Google maps for finding businesses, but that’s it.
Location - NJ, USA. Car - Kia Telluride with CarPlay.
