Yea, you can walk bikes around, sleds would also be possible, at some point I’d like to differentiate between sleds and shopping carts for e.g. moving over soft ground vs asphalt or concrete, sleds are better at the first and carts are better at the 2nd.
There are some issues with multi-tile vehicles that make them kind of a pain when you change directions, but it’s functional already, so no need to hold off on landing it.
