I don't believe the risks are "vanishingly small". Small yes - but not vanishingly so - and the impact can be large.
Take the scenario of a payload landing in a road that someone swerves to avoid - potentially fatal.
Some rough math and observation would suggest that the chances of any flight landing on an A road are circa 0.1% (see below) and in front of a vehicle - perhaps 5% of that.
I know at least one instance where a payload has landed on railway track in East Anglia - there is a lot less of that than road.
Math: Lets assume that we keep the flight well away from motorways and that B roads aren't a concern. There are 48,164 km of A roads in the GB - lets say they are all 6m wide. Thats 289 sq Km of road surface. The total area of GB is 243,610 sq km - so the probability of a payload landing randomly in GB on an A road is a little over 0.1%.
We could probably argue about whether this average is appropriate for the areas in which we land - but I doubt that it is wildly out.
Take a look at an A road in google maps to get an appreciation of the occupancy during daylight hours.
