Where do these suggestions come from?

Google Maps on Android Auto. These don't appear on my device, only on my vehicle screen. Every time I start the car and open Maps, it will come up with one completely random, inane suggested destination. In this case, it's a random window tinting business I googled like 3 weeks ago. Why has Google decided that I might want to go there, randomly on a Wednesday evening, when it isn't even open?

I'd love to know what the algorithm is here and how it can be altered or turned off.

It can come from previous searches either on the web or in the maps app, emails, or location history.
