Some time ago, an article made me rethink my view on the speed differences between cars and bicycles. Here, too, you have to pay twice with your own lifetime, because ultimately the time it takes to get from A to B is not simply the driving time, but you have to add to it the (proportionate) working time to earn the money you need to acquire, operate and maintain the vehicle: speed = (working time + driving time) / distance. Of course, the outcome of this calculation varies depending on the specific situation. I recommend everyone to estimate this once for their personal situation. In any case, I was amazed at what came out for me.
