No but think you will find traffic flows are substantially higher across UK than Dublin to Cork, aside from peak hours is there any Motorways that are continually busy. Issue with UK is that you have something like M1 300 odd miles, M6 similar, M5 close to it.I wound not expect PH or BK to open 24hours - just the service station itself should be 24h. After that if these companies choose to set up shop then we should obviously let them in. I am a sure they would jump at the opportunity.
Are you suggesting that there is any stretch of motorway in the UK as long as Cork/Dublin that doesnt have a service area?
The problem with the existing businesses is that they are in the wrong location - but they should be given the chance to tender for the new location.
Issue of service station can be tackled by signposting 24 hour stations with 2-3 kms of exit with a requirement of 7 day opening.
Service areas are a waste of resources when not needed.
