There is a code of practice for the roads (Highway Code[0]) and for the waterways (Col Regs [1][2]) apply more informally. On the river you stick to the starboard, use appropriate nav lights after dark, don't create breaking wash and stay under 8 km/h. On the road you don't run red lights, cycle on the pavement, cycle behind reversing vehicles with limited visibility mid-manoeuvre, collide with pedestrians, etc etc. As someone intimately acquainted with both the Oxford waterways and roads I would say that road users in aggregate (mostly bicycles) behave far less lawfully, predictably and safely than users of the the Thames! If I were designing an automonous vechile I think it would be far easier to do it on the water!
