In chorus and disputation slight with others below,
I am of the views:
1: ref UK Motorway Minimum Speed Regs:
Under std conditions, without local restrictions (for road works say) and excluding special (v heavy say) load movements:
Me understands it is 40mph.
2: ref General Ethos of Auto Piloting et al and its Legal Status:
I respectfully and most humbly submit:
As is to date, it's legally bollocks m'Lud.
Ipso F (and you too if that came to mind):
On nearly all occasions of prang:
We will know who the injured party is; that being common to most accidents/incidents.
Where auto vehicles are involved, whether they be the agreed* perpetrator or even the injured party after being clouted by another same/similar:
We just don't know who to blame for said prang unless it can be proved that the offending vehicle's occupants:
were at time of prang / had been previous to prang / are in knowledge of other,
fucking about with the manufacturers pre-sets.
Manufacturers and sellers are putting these systems to market with such labyrinthine conditions of applicability that deconstructing the warrantees of any,
by any, especially the end user buyer/hirer etc, is, if not impossible, most certainly impracticable by, again, the end user/hirer*.
The poor sod who,
if he hasn't modded the system and has no knowledge of other(s) doing such,
has put the vehicle to road under the recommeded conditions he was briefed with at purchase / start of hire - etc.)
therefore should be blameless but will undoubtedly be the first to put to scrutiny).
