IMO those cars are pretty smart, so long as we don't have a bunch of other oversize vehicles on the road. I don't think they're any more dangerous than a motorcycle.
To help economy, we need to go smaller. Most people in my area don't ever use their extra large trucks for anything they need an extra large truck for. And people that buy large vehicles to be safe are selfish. For example, the damage my Bonneville did to the Toyota Matrix that collided with it was incredibly biased. I felt nothing, and there was very little crumple. Their wheel came off, it bent their frame, and bent body panels on the opposite side of where I impacted it.
Smart car isn't designed for rural areas or huge highways. It'* for city use, like in Europe where it was designed (I think).
