I occasionally take a Lyft Line / Uber Pool / similar from airports. This was from my last ride.
The other rider was asking a bunch of questions about Seattle.
Him: How long does it take to get from Kirkland to Downtown Seattle.
Me: Plan on ... like an hour.
Me: What brings you here.
Him: I've got an interview here.
We ended up chatting about traffic in the area the rest of the way. Super safe conversations.
