So the figure is accurate.
If bikes could park like cars and be safe, a lot more people would use bikes for errands. As it is I only use my bike (even my cheap one) when I can keep eyes on it from the store.
I live in an area where I can very easily and quickly bike to just about anything. But I never do because there's nowhere to store the bike while I'm there so it will get stolen. So I either walk (if I have the extra 15-20 minutes) or feel silly driving a mile or less. I'd rather bike.
But if you buy a $5k electric cargo bike and it gets stolen two weeks later, or you have to spend 10 minutes finding a secure place for it everywhere you go...
Even the highest end technical fabrics don't work very well when it's humid outside, which tends to happen a lot when it's raining.
If you're actually working hard, you'll be covered in your own sweat soon enough. Given the choice i usually just go with the rain instead.
Riding an ebike is a different matter, that's probably entirely doable with current tech.
