Velomobiles are a non-starter for me, and I bike everyday.
If we were sane in the country the right approach would be to steadily increase gas, GVW, and/or mileage taxes. Driving is so darn cheap today that people don't think twice about driving monster SUV's for 20-40+ miles one-way to work (and still call it a "good" commute). When gas spiked over $4 a while back people actually were downsizing cars and thinking twice about their long commutes, but after a few years of $2.50'ish gas SUV's are back with a vengeance.
As much as taxes suck, people don't change behaviors without strong incentives.
A lot could also be done on the education front to educate both drivers and bikers about the rules of the road and how to get along, and to assure new bikers feel safe and knowledgeable.
We are right in the midst of the annual spring "fair weather rider" apocalypse around here, where the bike lanes, car lanes, and side walks get filled with hapless well meaning folks riding the wrong way, blowing through red lights, entering the bike lane from the side walk without warning/checking, stopping in the middle of the bike lane at random, etc. I hate most cyclist almost as much as the drivers do right now.
