Using a similar metaphor, I'd compare Go with a jet that's high performance but easy to fly - i.e. it doesn't have the numerous gotchas and quirks high performance jets usually have that the pilot has always have to keep in mind to avoid shooting themselves in the foot (aka making a hole in the ground :)).

E.g. it won't let you overload your engine by using a very special feature that lets you get away with it, but it'll let you fly fast and enjoy afterwards how trouble free the experience was.

OK, I think I'll stop with the mataphors now :)
