What is the fastest, you have ever driven on a highway. 110mph i probably would have gone...

I've touched 80mph once or twice, and only briefly, but my car's not really built for Autostrade speeds. That was probably overtaking downhill on a motorway, to pass one 40tonne lorry overtaking a couple of others at their speed difference of 3mph.

More importantly I do not intend to break the speed-limit! It is just not worth risking a hefty fine, probable "points" on my still-clean licence, and increased insurance premiums; just to save a few minutes that rarely need "saving".

I applied basic arithmetic to a journey I take occasionally, of about 310 miles each way with 210 on the motorway. The other 100 are on ordinary roads with many obstacles and speed limts.

The difference between 70mph and 60mph maintained throughout that entire motoway stretch is only 30 minutes!

So insignificant. (The arrival times on these journeys are not important. If they were I'd obviously start an hour earlier.)

It is of course impossible to achieve such driving in reality, and the mean speed for these journeys is <50mph, even with minimum fuelling and "T&P" stops to a minimum.

The significant difference is in fuel consumption, of course. I've not measured it but my car's most efficient cruising speed is probably 60-65mph.

The spped limits in the UK are 70mph on motorways and dual-carriageways, 60 on single-carriageway roads, except in built-up areas or where otherwise stated.

I recall seeing 110 on the speedometer while barreling down the country road to my father's ranch house when I was a teen. Unfortunately the big magnetic business plaque on the side of the door to his Ford Silverado was never to be seen again.

120. Many years ago in my Chevelle SS 454. It's a bit of a careless story. 🫣

130ish on accident. I wasn’t paying attention to my speed, and it was a quick quiet car. When I suddenly realized it wasn’t that other people were driving slowly, I slowed down 😂

not sure, speedo was pegged at 165 & I was still accelerating (c3 corvette with a hot motor); getting there was easy... slowing back down was a bit hairy...

Driven, 100. As a passenger my dad hit 130 on the highway in an old two seater convertible he was working on with no floor. I was maybe 12, feet on frame in the back area watching the drive shaft spin believing I was going to die.
