The necessary approach is to build highways and transit. Both are the solution. None are the problem. The population is increasing and so is demand for transport.
Some trips can be better with transit, others are better with the car.
Highways criss cross Europe too. These enable enhanced connectivity. Its all about a balanced approach.
Highways, rail, cycling, and air transport all work together to relieve pent up demand. They are all solutions and should be enhanced. Having more capacity and more options helps everyone because it allows more movement in a society.
