That's an interesting article, thanks for the link. I'm not sure I agree with computing the numbers per hour instead of per mile but it includes the exercise angle which I wasn't thinking about.
That might be a bit of a stretch, but the odds of someone biking 70 miles to work vs driving 70 are pretty low. Mostly if you choose to bike to work you are going to live closer. I used to bike ~20 miles from Downtown Baltimore to Columbia, MD for work once or twice a week and it was always fun and a great time saver because you overlap your commute with your workout. One thing you discover is that even with all the highways the old backroads are still there. I managed to find a route that was pretty scenic and mostly car free, except the part of the route through the city.
Here's an old blog post of mine with my old route:

I've been a cyclist for 40 years. I have had one serious accident (concussion, about 5 years ago) but it was me being stupid and there were no cars involved. I've ridden tens of thousands of miles including twice across the US, and on all sorts of roads (even interstates in some places), dense urban areas (San Francisco, downtown DC, Baltimore), winding country roads and you need to keep your wits about you but I've never really felt scared or threatened.
Europe is definitely more bike friendly, but it's definitely not as dangerous as people intuitively think.
The more people bike the safer it's going to be.
