McDonnell proposed the hybrid tax as part of his transportation funding plan, which includes other bizarre proposals, like making Virginia the only state without a gas tax.
Thanks to the outcry against the hybrid car tax, that measure was stripped from the House bill reflecting the Governor's transportation plan. And while the Senate failed to pass a transportation bill before the "crossover" deadline, the two new versions of the Senate transportation bill that were offered by Republican senators, Senator Newman and Senator Wagner, both stripped the hybrid tax as well. Therefore, it seems unlikely that this punitive tax idea will be added back into the transportation plan. But never say never!
