> Governments are also rolling out regulations, such as bans on tour buses in Rome and gating-and-ticketing in Barcelona. The ban on tour buses might actually end up being counter-productive, if that one bus is replaced with many more smaller vehicles that in aggregate take up a lot more space on the roads. A better solution would be a universal congestion fee that all vehicles entering the most congested zone pay (and yes, the fee for large vehicles like buses would be higher).
