OUTREACH Having done my 10,000 hours thinking about the challenges of increasing ridesharing, I think the biggest challenge is that people are not oriented to doing it. Their ‘default’ setting is to jump in the car and drive. It is not that they would not be a passenger, just that doing it generally takes much more effort than the alternative, and the payoff for the greater effort is perceived as being too low (although in many cases they do not know the true costs of the trip). And the effort/reward imbalance is still the case with the smart-phone variety of instant ridesharing, and online ride-matching services. On the other hand, as a result of focused campaigns, peo-

ple are buying compact fluorescent bulbs, separating out recyclables from their garbage, reducing use of plastic shop- ping bags, and caring where their second-hand smoke drifts. I am encouraged by evidence that Millennials and others are increasingly giving weight to the environment and other common interests in making their personal travel decisions. We need to expand on these trends. I think the success of those other campaigns holds lessons for ridesharing: the combination of community education, appropriate regula- tion, and above all making it easy to do. I challenge this community to come up with the mecha-


nisms that enable these sorts of results for passengership, whether they fully involve technology or not.

A DEGREE OF AUTONOMY This has been a year of excitement about autonomous cars (the subject of no less than three articles across the two regional editions of this issue of Thinking Highways). What fascinates me about this newest form of intelli- gent transportation is the ways in which some proponents
