There is no good alternative to oil for transportation that we have
yet...., it should not be wasted.

One good alternative is LNG/CNG. It's just missing infrastructure,
something that has existed in Europe at least since the 70's. Another good
(but expensive) alternative is hybrids such as the Prius, or Explorer
(taxis in NY City). If NY taxi drivers really had problems with them they
would have said so, and I have asked.

LNG is not a good solution at all. It doesn't liquefy at normal temperatures
and must be vented. Talk about GHGs! CNG isn't dense enough to be useful
(and the container too heavy). If it were just a matter of delivery
infrastructure you'd be seeing it now. It's not. ...and if it were, you'd be
fighting that too.
