Transportation researchers have a tough job. They're always trying to promote things like public transit and small cars — and everyone's expectin' it ta save the planet or something. Take, for instance, the CLEVER (Compact Low Emission Vehicle for Urban Transport - yeah we know it's a "U"), a three-wheel concept from the University of Bath. It leans into corners for more stability, runs on compressed natural gas, and is narrower than a Smart. And yes, it could totally make large cities cleaner and less congested. That is — to borrow a British term — if we were all willing to look like even bigger tossers than scooter riders.
