In general I completely agree that updating infrastructure to create dedicated spaces for non-car modes is the only way forward. But given how politically difficult it is to change--and especially to take away--existing infrastructure, and how much easier politically it is to introduce new tech, I hold out a smidgen of hope that driverless cars might help us inch in the right direction. Because they'll be managed by companies rather than individuals, they almost certainly will be required to adhere strictly to speed limits and other traffic laws, can be programmed to give bikers and pedestrians a wide berth, and won't (I hope dearly) get road rage. With luck and a sufficient volume of autonomous cars, this could help more people be comfortable riding with cars until we can get enough political will to build some decent infrastructure for non-car-users. And at this point I'll take what I can get to keep the ball rolling (and hopefully accelerating a bit) towards a friendlier future.
