130km/h is just ludicrous. The consumption compared to 100km/h is about 50% extra and the time saved is wiped out with just one bathroom break.


My typical drive to visit family is roughly 125 kms with a 130 km/h speed limit and 125 kms with a 110 limit. If I drove at 100 all the time it would take 25 minutes more. More than a bathroom break I think.

Honestly I feel that driving faster is safer for me, since I tend to zone out if I don't have to pay attention to overtaking trucks.

If you don't drive while being sleepy this is just a matter of getting used to it. I used to drive to family visits 160-170km/h, but switched to 110 km/h (or train+bike depending on the circumstances). It feels slow at first, but you get used to it. The same when you do it the way around.


But that bathroom break is going to happen anyways


Depends on the car. With a V6, it’s pretty negligible.

My SUV gets better mileage at high speed cruising due to the gearing. As long as you’re not constantly accelerating/decelerating and going with the flow.

what model would that be?

this can save even more fuel, if your SUV still uses fossil fuels and you accelerate at the optimal engine load and then glide. It's called pulse and glide.


Honda Pilot. I find myself taking the same 3 hour drive every couple of weeks this year. With the cruise set at 65 or 85, you’re in 10th gear (iirc) and there’s no significant difference. Variance is more driven by traffic in the city.

Once you start working the pedal, mileage drops ~20%.

That's a big safety and pollution problem in itself.
