OK, now my three, a lot like what's already been posted:
1. Mass transit that's bike-accessible; imagine, a train that took your bike aboard that rolled you from Indianapolis to Moab! A lot more focus on mass-transit travel goes hand-in-hand with this.
2. STRONG education for drivers; eliminate the sense of entitlement that seems to now seep up out of the upholstery.
3. Cyclists have preferential treatment on the road, not car drivers.
