Or just avoid the CTR and get something that has torque lower down the power band. 4k rpm + at motorway speeds will become tiresome very quickly, there's nothing more irritating than a car that wants to be raced when all you want to do is drive.
You have just summed up my reason for choosing the LCR over the CTR. I spend a fair bit of time on motorways or dual carriageways and with this comes a lot of overtaking. In the CTR it was a case of put your foot down and wait... wait... wait... past it, or drop a gear and go around the car at high revs then change back up again to cruise.
In the LCR, and any other car with torque, you simply push the loud peddle more and off you go. Once past the car you ease off the peddle and cruise again. No gear changing required.
