Will they have to bring a huge trailer mounted diesel generator behind a heavy tow tow vehicle to demonstrate how "green" the car is?

The Tesla roadster has a range of about 250 miles on a full charge. Heavy-footed use may decrease that by 20-30%, so it should be able to drive 25 easy miles to the stadium, run 100+ hard laps on the longest track we have ever thrown there, and still make it home with battery charge to spare.
From the above you may guess that from an engineer's point of view I'm not a fan of EVs or hybrids. If we really want to save fuel we should all be driving modern turbocharged smart diesels as DDs like they do everywhere else in the world where fuel is expensive.
Reducing petroleum fuel use through efficiency is not the only goal or appeal of EVs. Economic and political considerations for reducing our dependence on foreign oil imports is only one aspect of the problem. Reducing greenhouse gas emissions is important as well, unless one chooses to deny the scientific evidence of global climate change from anthropogenic sources, which is a popular strategy among fundamentalist Christian creationists, conservative talk show hosts, and former female vice-presidential candidates from Alaska, who shall remain nameless here, but accepted as fact by 97% of the experts working in the field. For the nation as a whole, the total greenhouse gas emissions from our US light duty vehicle fleet are expected to be reduced by 27% from the projected penetration of PHEVs and BEVs. In areas that do not depend on coal as the source of energy (like San Diego and most of the west coast) this number is more like 40%.
Despite the FUD being spread around, there are
careful, unbiased studies that you could appreciate from your engineering POV, which calculate these benefits and estimate that we could power 73% of our LDV fleet in the US without major improvement to the utility grid by utilizing off-peak generation capacity. Higher utilization of total grid capacity will result in reduced average utility costs for everyone. It is a win-win situation all around, and we have to start somewhere. I am the last guy who wants to give up my gas-guzzling hot rods, but we can't continue to pollute our planet and spend massive amounts of our money defending our oil interests in foreign countries forever. It is an unsustainable path we are on, I believe. I am going to try to do my small part by at least converting my run-around-town vehicle usage to electric power.
