Sometimes I feel like Austin (hell, Central Texas) just needs to declare a Transportation Emergency and appoint (or elect) a Transportation Fascist. That position would have absolute authority to bypass all the usual red tape (public input, environmental impact, contractor bidding, property disputes, etc.) that make transportation projects drag on for decades.
Also, we need more efficient ways of dealing with accidents and disabled vehicles. Rapid-response crews with bulldozers or heavy-lift helicopters that can move wrecks and disabled vehicles out of the way in minutes, not hours. And let's get big, slow-ass construction vehicles and heavy commercial vehicles off city roads during peak commuting times.
Finally, I don't want to see any fuckin' orange cones or barrels in a travel lane unless there is actually work happening there. How many times do you see a lane that's closed for a mile and absolutely nothing is going on, and the surface is still completely drivable?
