I'm not sure if "convenient" is really the right word for it. I recently moved to a new job, and my commute is now 20-30 minutes by car. My new office has bike facilities and showers, and isn't too far from public transit, and is generally about as optimal as you can get for non-driving commuting in this city.
I still drive because biking is A. pretty physically grueling in a number of common weather conditions ( greater than 100 degree or less than 32 degree temps for much of the year, carrying my bike up 2-3 flights of stairs... ) B. Going to take 2-3x the time per day, before time spent showering on each end of an hour-long ride in brutal heat... Public transit is a 1+ mile walk/ride on either end of it (same problems as above), means I can only get in/out of work at specific times, and still takes 2-3x longer than driving.
That's before we get into the 2000 serious injury-causing accidents that people get in on bikes per year in my state, many of which are in my county. I really hate cars, but I'm mostly driving slow and on low-speed roads. I'm very unlikely to die or be seriously injured. That's not something I can rely on on a bike commute.
I'm looking to move closer to the office so I can mitigate some of these because I earnestly hate driving this much, but I wouldn't claim that that's going to make biking/walking "incredibly convenient", just acceptably less inconvenient.
