148th Ave is a nightmare from like 4:00 p.m. to 6:00 p.m. every weekday. I try to avoid going anywhere near it during those times, which means I don't do any shopping at Fred Meyer or the stores around it at those times, which means I'm just chilling at home not stimulating my local economy.
I don't care much for Microsoft products, but I think they've been good citizens in this respect so far. Private companies can't initiate road construction projects independent of the government, but they've worked with the city of Redmond, have thrown money in the pot, and have created a private shuttle service that goes all the way to Seattle and helps take cars off of the road.
