I&#x27;ve lived in two European cities with extensive tram lines. Both of them have trams on the streets, but the other one also has dedicated lanes in places where streets are wide enough. The dedicated ones are very fast and enjoyable to ride, but even the on-the-street lines are way better than buses.<p>Blocking the rails happens very rarely, so I assume it&#x27;s about everyone getting used to it, plus hefty towing fees.
