Ask HN: How did Google know I clicked SiriusXM in my car?

2 pointspitzips2 comments

I clicked the SiriusXM button on my 2014 Mazda Infotainment (not Android Auto) for the first time since buying the car in 2015.

5 seconds later I received an email from Google Nest for a 3-month trial for SiriusXM. Was this an extremely random coincidence? How was that possible?

You have a Nest to integrate information about you. It works. You have an infotainment system to link your digital life to your car. It works too. By "works" I mean selling you stuff.

Was it to the same email you had when you bought the car?
