For us Texas people, since I work in goverment (technically) I usually get the latest info on transportation laws coming out of Austin. As it applies to the Leaf, there are two proposed laws to follow that will be quite benefical to us:
HB 3310 - A potential $4,000 rebate on the purchase of a plug-in vehicle (a leaf will get the full amount). This bill is currently on the schedule for House floor for vote.
HB 3308 - Plug in electric vehicles (including the leaf) will get a free single occupancy ride in all HOV lanes in Texas. This bill passed the House and is on its way to the Senate.
As a small note, both of these, if passed, become active September 1, 2011. The HOV use would require acquisiton of a sticker that would be placed on your back windshield to denote your qualification as a SOV user in an HOV lane (easier for enforcement I suppose). As for the credit, it would work as any rebate. Proof of purchase or something like that and the state would send you a check afterwards. The only problem with this one (if it becomes law) is start date of September 1, meaning all vehicle purchases before this date would NOT get the rebate check. This would exclude all the early adpoters in the first round of reservations and deliveries, but could apply to the second round of people; but this could be changed as its filtered through the House and Senate (as well as the rebate amount!).
Hopefully both of these pass! I know I have been jeleous of the California people and thier 5k rebate as well as the Orgeon/Washington people with the no-taxes on thiers. Finally, Texas might get some more incentive!
