Road Trip!!!

I thought this was an interesting factino:

You may have seen this already. Americans cut back on driving in March, compared to the previous March, more than in any single month since such record-keeping began in 1942. It was a 4.3 percent drop in miles driven, a reduction of 11 billion miles.

hmmmm...

if a 4.3% drop is 11 billion miles then... (whips out calculator) 11x10^9/0.43 = 256 billion miles/month * 12 months = 3 Trillion miles/ year!

3 Trillion miles is half a light year. The US drives half a light year every 12 months. And thta's just the US! Assume thats about a 1/3 for all planetary driving.... 1.5 LY!

Wow.

We could *drive* to Proxima in less than 3 years!
