You're essentially saying that legality and practicality are usually aligned, in practice. But of course, an example like a kerb is a barrier that is impractical to ride over, but not illegal. Or barriers could be erected by bodies that don't have the right to impose laws or bylaws. > There are quite a lot of barriers which are vehicle=yes on both sides, but > vehicle=no for the barrier. Both legally and practically. Heh, good point. I should know, I live in such a street! (Or another example, a service gate at a swimming pool: the public can be on either side, but is not allowed to use the gate.) So, to summarise so far: - legality and practicality of crossing barriers are distinct - legality and practicality of crossing barriers are also distinct for different modes of transport - legality of crossing a barrier is distinct from legality of being on either side of it. >The problem with using an access tag on a highway which is also a barrier is >that the access tag on a barrier goes perpendicular, but the access tag on a >highway goes along the way I think this would only be a problem when a highway shares a way with a barrier. This could happen, for example with a fenced-off tramway. In that case, the two meanings of "foot=no" would actually be aligned: you can't walk along the tramway, nor can you cross it. But there are probably cases where that doesn't work. (I guess a fenced off bike path, if that exists, would be in that category: you can ride along it, but not across it). Maybe "bicycle=yes" and "bicycle:crossing=no"? Eurgh. The limitations of key/value pairs.
