3500 ft drop over 13 miles. I-80 down from the mountains into Salt Lake City. Curvy canyon road, but built to interstate specs so the curves were wide and not too sharp. 2 AM so traffic was almost zero. Speed got slightly above the limit, but no more than you'll find every day on most highways.

Daily I have a 1-mile coast if lights and traffic cooperate.
Here's another one I've done, 2000 ft drop over 12 miles. Cabbage Hill in Oregon.

3 Miles through 10 stoplights. South Lamar, from the Golden Corral @ Panther Trail all the way across Town Lake and down the loop to 1st St.
I used to do it on a regular basis. I know they re-timed one of the lights (@ Barton Springs Rd.) and I think they re-timed a couple others, too. Haven't made it in almost a year

I have a section of my daily commute on the way home that can be as much as 1.1 mile if traffic is 'right'. Top of an overpass, cut the engine at 60mph at the top then coast down to my exit, spin around the cloverleaf and coast up to the first traffic light. If I'm really lucky I can hit the light green, do a bump start and never even hit the brakes or the gas! Great feeling when everything happens exactly right.

Afton mountain between Charlottesville and Waynesboro, probably 3000 foot drop in 5-6 miles maybe more. The grade was so steep there before they built I64 I had to downshift my 63 Valiant to 2nd gear because it did not have enough power to go 45 in high gear with a 101 HP slant 6. That was 1967.
In my VX coming back from Blacksburg I was drafting a big rig at 85 MPH and actually had to put it in 5th gear, then 4th gear to keep from being sucked into the trailer, at 85 MPH. That coast was 3 miles +.
regards
Mech

I-90
About 3.0 miles. You get on the on-ramp, get up to 35ish, and coast. I don't EOC, but in neutral, it'll hold 70ish. At the end there, it comes up a little bit, then back down to the merger of the highways, overall about 4.5 miles with maybe 15 seconds of accel.
To the north going across the top of the park, there is another road that has a significant drop. However, the end is a blind corner with an immediate stop sign. Too bad!

There are several back roads where I can coast for 1-1.5 miles, but the hills around here are too "rolling" for really long coasts.

The only hills that I drive are too and from my parents' house and they would be too steep to kill the engine if I did not have an automatic. I spend much of my time in-gear and sometimes need to downshift.
All of them include curves, too, and I do not know if I would want to try without power steering.
