IMO the easy solution to the problem of brake lights on the freeway is to leave more following distance and then only ease off the pedal slightly (<30kW regen).
12,000 miles / 6 months and still getting used to it. I have resisted the urge to turn it down to low. My problem is that I drive at least 75% on the freeway and most of the time it's moving fast, but with heavy traffic, brake lights do come on. When that happens I still instinctively drop the accelerator pedal and move my foot over to cover the brake in case I have to stop fast (usually don't). This, of course, causes the car to essentially "brake" instead of coast. I'm a little worried about what will happen next winter when the roads are slippery.
I find the re-gen quite agreeable on surface streets and non-freeway highways where there's lots of time to modulate the pedal as you drive. That's a lot different than driving 70 - 75 MPH in heavy freeway traffic and having a line of brakes come on ahead of you.
I wish Tesla would implement a speed-sensitive setting for re-gen (and for the steering effort too, for that matter).
