Regarding the giant trucks specific: one pragmatic lever we could pull here is just m parking enforcement. The EU says we have to allow sale of dangerous vehicles to keep Trump happy. But cities can just say "you can't park there mate" (where "there" means, for example, the Paris metropolitan area). They are already too big for existing parking spaces. We can forbid construction of larger spaces and require privately-owned car parks to enforce size limits.
