It might make sense for Google to do that, but they don't owe it to truck drivers or anyone using a free app. It doesn't benefit Google — it doesn't collect your data or serve you ads — if you don't use it.

Why is it not a problem at all to use one app, but some kind of huge burden, compounded by the all of the info on the dash, to switch between two apps? They don't need to have both active at once.

Yeah I'm not saying they can't use Google Maps. I'm just saying it's part of their job to drive safely and follow the rules of the roads they choose to use. However they want to get there is fine with me. But they're the ones causing the problem when they don't do that, not Google Maps.
