We have those inner city bike extremists here, too. There's proposals like banning all motorized traffic from the city because you "can walk to your bakery duh". But they never ask themselves how the baker gets all his materials to the bakery.
This perfectly legitimate argument for Oxford would be silly to make about say Milton Keynes.
I have a trailer for the bike, we can haul 100 lbs. it’s more than enough.
Businesses can be allowed to get deliveries, just personal cars are restricted.
In my city, many businesses have switched to operating from a cargo bike: plumbers, electricians, even mechanics.
We’re doing both: buying what we need in large quantities or with a long shelf life once a week from a supermarket and things like some meat, fruits and vegetables from the corner shop but that takes a bit of work and planning. Still, there’s money to be saved taking advantage of economies of scale.
You can allow transport for business (speed-limited to 30 km/h or ~20 mph) and ban individual's cars. There are busses, trams and subway and there is no need to have a car.
The condescending assumptions people make when they dont have arguments are getting absurd.
WTF? In inner cities, bikes are the sensible option for 90% of traffic. Not for emergency services and larger freight of course, but it's possible to aim for a sensible mix.
