Driving a car often involves the use of a long, flat surface - also known as a road!
If you've ever driven across a field, you and your neck no doubt appreciate the abundance of roads that now criss-cross the country like a big, dropped, bowl of spagetti.

Roads were invented by the Romans, an ancient race of people who lived in England two-thousand years ago. They built them from logs - which is why many Roman roads were straight: you try finding enough curved trees to build a road!
I tried to find some curved trees once, but I could only find five. And there was a possibly vicious squirrel living in one of them!

Today, roads are made from a material known as 'asphalt'. I've no idea what is in asphalt. Stones and PVA glue, I expect.
Whatever asphalt is made from, it is a far better material than logs.

But even the greatest material wouldn't stop drivers having accidents. Drivers are always having accidents, due to mostly being idiots.
And no-where are drivers more idiotic than on the road between Lille (France) and Toulouse (France) - the most dangerous road!

It's dangerous due to frequent rock slides, and a sheer drop of several hundred metres on the left hand side.
And also because all the drivers are French.
