Knowing how to play the violin is actually a very important skill to know for driving, there's a lot of cross over knowledge there. In my country we make sure people can play the violin, drums, and at least two wind instruments before allowing them to apply for a license, but the catch is you also need to know guitars to get any car insurance that's worth something, most places any guitar is fine but some places INSIST that it's an acoustic guitar.

In the end, it's all worth it, it makes driving a much more rewarding experience, but hey, you can always ride a bike around for free!
