>You can't design a city for both walking and bicycles.
Your assertion shows that you have never visited a Dutch city.
Most Dutch cities were originally designed for walking (they are old, at least in the core), then (like most places) the car took over in the 30s - 70s, but since the 70s there's been a concerted effort to re-establish bicycle supremacy, along with strong public transport.
The outcome is that pretty much everyone (including the elderly) cycle everywhere because it's most convenient. And walk around perfectly fine once you've parked your bike. And if you need to go a bit further afield when you're done? Jump back on the bike.
The hybrid of public transport/bike/walking works incredibly well, everyone co-exists perfectly, without making any compromises. Obviously, this wouldn't happen without there having had been a concerted effort to build good multi-modal infrastructure nationwide for the last ~50 years, but it really pays off. The urban environment is really nothing like pretty much anywhere else.
