Of course not, Ms. Chow.
We've come a long way, but the newer generation wouldn't know that at one point you couldn't do that, and now you can. How complicated is that compared with the European model?
I want to get back to Mr. Shaw on the same question: why haven't we had the proliferation of vehicles into, say, natural gas? I also want to come back to you on this notion of how difficult it is to flip a switch. Frankly, I've never driven my own vehicle in Europe, although I've been there several times, and I would like to have a sense how hard it would be. Is it the same process as learning how to pump our own gas?
