Any thoughts you may have that "it can't be safe!" are probably right.
About this creation
My first ever 3 wide! It is still minifigure compatible, even accommodating three of the blighters, one for each stud width. Ok, so maybe they aren't comfortable or safe but they are in there. This was a nightmare to build, it isn't exactly strong, fragile would be a good description but it does work, it even has control levers (that actually do steer the front wheel) in the front, about which I'm pleased. I could do with reducing the colours to a strict 2 but the bricks to do this aren't spare. I'd like to do it in yellow and black, like a Bombay (Mumbai) taxi but what I like and what I get rarely match.
