Just a comment regarding the time estimate: For hybrids, travel times would likely approximate "regular" travel times because drivers probably won't stop and wait to recharge the battery once it's drained. The cars use a different battery to start the car, so they will still be able to start the car when the "main" battery is drained. As such, they'll just refuel and continue driving using only gasoline until they have time to recharge the battery (i.e., a mini/booster charge during a food stop or a complete charge when they reach their destination or stop for the night).
