I should add to my above post internally within the Highways Agency in the UK there is a great deal of uncertainty over what to do with driverless cars and cars with computer safety measures because of political involvement and public perception.
In theory if all cars are made driverless and computer controlled, then the car can maintain whatever speed we determine is safe, and given the reaction time IN THEORY they could mean speed limits as we know them are a thing of the past and that speed limits across the board could raise for such vehicles. The problem with his is that it is completely at odds with the aforementioned campaigning and political drive that speed kills!
can you imagine if in 10 years time motorways could have a limit of 100mph, urban areas 50mph as the driverless cars could stop almost instantly, with cars following doing the same safely? its hard to imagine it with how that message has been drummed into us
Oh my god no.
Also this is the LEGAL limit. Professionals set these limits for matters of safety, and you will be pulled over for going over the limit and charged a 100+ dollar fine for Breaking the Law.
I'll just point out that, whilst we professionals are meant to set the speed limit based of off existing evidence, Political pressure can and does play a huge part in this - If an MP/Councillor etc (on the US's case I'm sure, Senator/Congressman etc) demands that a lower speed limit be introduced and they have enough political weight and/or public following then you will find your management tells you to do as you are told for the easy life, its happened to me before and I've put a speed limit change in that's not appropriate and its exceptionally frustrating as it practically encourages motorists to break it.
I really feel there should be some legal separation to prevent politicians from doing this, its incredibly frustrating when someone's perception and belief trumps empirical data and evidence
