I would love to bike because if this. I sit in traffic jams all the time. But even with the car, I drive 40 Minutes. Wait, let me check how long I would need with the bike. Ah only 1h56m :) Yea not gonna do that. I'm faster at home even with traffic jams, and they are not every day.
No matter the infrastructure, it takes a while to go 15 miles each way. Granted, its more consistent (with an ebike at least). At the extreme end, the drive to work has taken over 2 hours once. So biking would have been much faster. Most days is like 15-20 minutes for the drive vs 55-65 minutes for the bike ride
