I didn't understand the direction of latest posts so turned back to the OP and read forward.
I cannot for the life of me understand why this thread is in the HSR section.
Perhaps we should have a 'local transport' sub-forum?
The reason for it being in the HSR is because I asked the question as to whether car Automation would negatively impact on HS2 (as some think, mostly those opposed to HS2) or whether it wouldn't. With the latter it could even improve the case for HS2 as less and less people owned their own cars and automated cars potentially had limited range.
