You do realise that Brian is blind?
Which begs the question of what the licensing situation will be like when fully automatic self driving cars which can drive themselves anywhere become a reality.
Will people like Brian, who is currently disqualified from holding a licence, be allowed to use such cars?
And it would add a whole new dimension to the school run when all the 5 year olds turn up in their cars! Perhaps they could have a 'return to base' button so that their mums can have the use of the car for the rest of the day?
