Personally, riding a motorcycle has made me a much safer and relaxed driver, if only for the reasons that mine is ruddy slow and the mirrors are useless. I'd like to think that I'm a better driver than yon average motorist, but being a self-deprecating Englishman, I'll never state it as fact.
As for merging, I'm always on the look-out for these signs:
Whilst everyone is roaring by on the left, trying to battle their way through the traffic to the front of the queue, I'm poodling along in the right lane, knowing that I don't have to merge
