That would be a neat trick since both of my grandmothers are dead! But yeah exactly the infrastructure is not only not built for biking but pretty hostile to it as well, not to mention that there is usually no dedicated space for storing a bike on location and theft is pretty high for bikes. The change to make biking viable is possible but the amount of inertia is high and would be at least as difficult as implementing widespread EV changes I would guess

We've chosen to allow it to continue

this is true, and would be good at least half the year so fair point but still need a good alt in winter. Still, cutting out half the year of car commuting is a lot better than nothing
