Price of gas, vehicles, upkeep, taxes, etc. If companies like Elio motors actually get some of the car/motorcycle crossover vehicles out it might change the trends. I think Elio has the best chance because of the price point. I like the vehicle Lit motors is bringing out but it's way over priced. The target needs to be $10k not plus $20k. I usually buy small vehicles but even they can run over $20k. I blame government regulation and the general unwillingness of companies to cooperate on developing cheaper integrated systems that are universal across vehicles for driving the price up. My '91 CRX SI cost somewhere around $12k off the showroom but I recently had to get a new daily driver so I bought the CRZ which cost about $24k. It's a two seater and has six airbags. The thing is built like a tank. Between the extra weight and required government add-ons it is way more expensive than it should be. While safety is an issue however when you drive there has to be an assumed level of risk. When someone drives a motorcycle they know they have a high chance of biting the big one in a wreck. All the safety stuff just makes the driver over confident so they don't pay attention to what they are doing. If a person's chance of death goes up I bet they'll put the cell phone away and watch the road.
