Actually no, if there are 10-20k people like me only driving a few thousand miles instead of 10-20k miles per year we'd be much better off! (which btw is the average in the US)
You aren't going to shame me over a few miles when I make a concerted effort to drive 1/10 of the average American, sorry.
But hey good news, Google is abandoning remote work and making its employees drive to and from work every day probably negating any benefit from this feature whatsoever.
It's about network effects. The more people we get to make the more eco-friendly choice, the better the place gets for all of us.
