Ban privately owned cars within medium to high density populated areas, improve public transport, expand railway to serve at least 90% of the population, remove street parking, and you won't have to deal with this stupidity anymore.
Don’t ban cars. Slowly start removing lanes and lower all speed limits to 30 kph until there’s just one left for emergency vehicles. Remove surface lots - underground parking is much more expensive. Improve public transportation. Impose congestion fees as % of net worth.
You're just describing the steps to a car ban 🤔 You might not officially call it a "ban", but removing any incentive to have a car achieves the same result. It's just a carrot approach vs a stick.
How does the emergency vehicle get past if there's a service truck making deliveries? Or is it a 2 land road situation? Or do they honk until the truck moves out of the way? I'm having trouble picturing it.
Procedural. Sensors on each block so the dispatcher can route the emergency vehicle around the blockage.
Have back alleys for a given neighborhood so that service vehicles can park without blocking emergency vehicles
Have delivery spots every couple of blocks. With smaller but more frequent stores, a couple rounds with a hand card would work fine. This would leave lanes clear
