It is so obvious that single-occupant drivers using side-by-side seating, thus taking up an entire lane on the freeway, is the precise source of traffic congestion, that any 3rd-grade kid can understand it immediately after looking at this graph. Why then are we wasting time and investing $billions in solutions that don't work, when the answer is so simple?
Maybe it's hard to imagine half of all commuters buying narrow vehicles to get to work.
Maybe it's not so hard to imagine that rather than spend taxpayer's $billions for building rail and widening freeways, that for a small fraction of the cost, narrow, freeway-capable vehicles like the Tango could be purchased and leased to commuters to give them the same mobility that they are accustomed to, with better safety, maintaining their private space to store items that they like to keep near them, and all the benefits of a car, yet able to travel at freeway speeds at over double the lane density of cars, instead of sitting in bumper-to-bumper traffic.
The Tango is the only product in existence that can solve the problem that is so well demonstrated in the above graph.
