I’m glad that we are sharing this part of our respective trips together. Here’s the thing. I’m going to go the speed limit no matter how close you get to my bumper.
If you would like to drive at the speed limit, too, then I would suggest adopting a safe, two-second spacing between our cars.
Would you prefer to go faster? That’s cool. There’s the left lane. It’s open. Go as fast as you want.
I wish you a safe journey.
Sincerely,
Your fellow traveller
