No. Only BMWs and the bugatti veyron can go past 100 in 2nd gear because they have extra-long gears.
I think it is a very good idea.

We could have a leaderboard of top-speed achieved in 2nd gear! Bouncing off the rev-limiter while taking photos, whats the worst that could happen?

I get to 65mph in second, then 100mph in 3rd.
It is until you need to overtake, drop it to 4th, HHHHNNNNGGGGGGGGGGG *5 minutes later* you're at 75 from 70.
I wouldn't bother. It's not hard to believe at all. By your logic, most multivalve 4 pot engines should be revving at about 6.5k at 70mph in top, to ensure they're 'in peak power'...?

I'm assuming peak power at peak velocity, not peak power at 70mph. No 1.6 Focus does 140mph.
Edit:
A 195/55/R15 tyre is doing 1,003 RPM at 70mph.
A 98 1.6 Focus has a final drive ratio (diff ratio) of 4.06, and a 5th gear ratio of 0.76, (http://www.carfolio.com/specifications/models/car/?car=25938).
So the gearbox output shaft will be doing 4,072 RPM and the input shaft (plus engaged clutch and crankshaft) will be doing 3,095 RPM at 70mph.
The peak power being at 6000 RPM, the car will be doing 135mph at peak power, which it wont, so 5th can be considered an overdrive on this car (roughly translated: I was wrong).
So yes, it should make a nice motorway car, at least in terms of noise.

Trouble is personal experience has given the OP wildly varying numbers.
My Alfa 156 is geared for about 3.5K at 80mph which means theoretically 5th gear is actually good for around 160mph which the car will never see. However that's the point, the car is revving less at motorway speeds, still well within the higher torque area of the rev range and thus giving a better driving characteristic. On most cars top gear is there to plonk you in the lowest revs which give you good torque at 70/80mph to improve fuel consumption.
That's where you've started to go wrong.

blurry photo at worst.

Think of the maths.
That means:
2.5k @60mph
2k @50mph
1.5k @40mph
1k @30mph
0.5k @20mph
0k @10mph
We also have the problem that 80mph on the speedo often means about 73mph real speed.
Sounds right. It was indeed 2K at 50MPH....
I am simply reporting what the tachometer read. I know what it read because Im a huge nerd who used to take note of such things when driving on the motorway.
As for speedo inaccuracy, mine wasn't that bad. Used to be about 2MPH over the GPS reading.

crash ?
I can do about 110 in 1st so makes testing a bit dodgy
Your car does 10mph with the engine stopped? That must be very economical.

I suggest you learn a little maths before trying to outsmart people with figures.
So if 2k is 50mph, how is exactly half the revs, 1k, 30mph?
