Well, the one I like best crosses the whole of Australia from northwest to southeast. It's about 4,500 km long!
Wow! How long does that take? These days the fastest cars can do it in six days. And what have you been doing recently? I've been building a new car with a team from Queensland University. We've done a lot of work on it, but we haven't finished yet. And you've been writing a book about solar cars. Well, so far I've only written the first few chapters! I want people to have a good impression of solar cars. But a lot of people think that solar cars are too slow or not very reliable. How can you persuade them of the advantages of solar cars? Solar cars are getting better all the time. They have reached speeds of nearly 80 k.p.h. In tests, one car we built has averaged over 40 k.p.h., even in cloudy weather.
