It would take less than 6 months to get to the Moon by car at 60mph (95km/h).
Astronomer Fred Hoyle was the first to point out that if you could drive a car upwards at 95km/h (60mph), it would only take about an hour to get into space.
To get to the Moon would take a little longer though since it's 400,000km (250,000 miles) away – around 10 times the circumference of the Earth. So it would take as long as driving around the world 10 times – just under six months.
Your only real problem (apart from the lack of air for your lungs and for burning the petrol) would be finding a garage to refuel – and that has a loo!
