Tricky to have a long weekend in Busselton without a car

But it’s literally called Busselton!

I mostly agree.

With the wineries, for instance, people drive up and down caves road to get to the places they feel like. But a lot of the wineries' cellar doors are actually clumped quite close together, no more than a 5 or so minute walk between them. So there is a fairly simple behavioural change people could make. The key problem is people aren't thinking in terms of visiting a small area to sample the wines from those few fields, they think in terms of individual winery venues.

Its also a problem that for most of caves road and the ancillary network, there is no pedestrian infrastructure. Not even between wineries and other venues that are clumped together. (M.River, and Duns townships excluded of course)
