Build more bike lanes.

To an extent, it's a self-solving problem. If you have great non-car transport options and an increase in traffic makes car driving less appealing, then more people will use those non-car transport options rather than joining the queue.

And an often forgotten point: this benefits people who have to drive cars too, since there are less cars on the car road!

The problem is that you may not have the room for it. The US might often have more room to retro-fit bike lanes, due to their roads be generally pretty wide. European cities, like Copenhagen have a massive issue as more and more people get things like cargo bikes and electric bikes. The bike lanes needs to be expanded to accommodate them, but there's no room. You'd have to remove cars from large parts of the city, which sounds great, except you do need to have the option to drive, either due to distances, public transport or deliveries. You can't do parking and have people walk, because there's also no room for parking.

For some cities I also don't see bike lanes as solving to much. Some cities, again often in the US have a huge area and millions of people. Distances in cities like Houston, New York, Los Angeles or Atlanta are just insane, taking up enough space to cover half of a small European nation.

ebikes mean you dont need to be that fit (or sweat) either.
