Fast roads/tracks reported as 140 km/h

[originalfoo]

Due to the way speed signs work in 10.21 and above, anything between 138 and 950 km/h will be shown as 140 km/h.

This is confusing for users, as previously (10.20 and below) they'd see the 'unlimited' sign for anything above ~130 km/h.

Example feedback from a Steam user:

Why is the highest default speed limit only 140km instead of unlimited as in the stable version? I asked the same question on the labs page.

I would say, it's not a bug but feature 😄 Now it shows a little bit more real speed of road/track than before

Current behaviour, speeds which cannot be represented by available speed signs are mapped to 140 (or 90 mph) all the way up to 950 km/h. Anything over 950 km/h becomes unlimited.
Old behaviour in 10.20: Speeds over 130 become unlimited.

Assuming we want to keep 140 speed as 140 sign, above what speed should we consider it unlimited? 143?

I would really miss the most beloved sign of the German Autobahn... Will it still be available?

I'm OK to restore the previous behaviour, it is 1-line fix

Copied from the PR:

Now clicking ⬅ on 5 mph (10 km) will show 🚫 and wrap over to 90 mph (140 km)
Now clicking ➡ on 90 mph (140 km) will show 🚫 and wrap over to 5 mph (10 km)

Where 🚫 = "no limit" speed sign (eg. white circle with black stripe for German/UK signs)
