The pit speed limit is 80 km/h(not sure in miles) so why do I get a penalty for going 80?
I wouldn't get a speeding ticket for doing 100km/h(speed limit on highways here)

That is because when u see 80 on the digital speedo it is actually a bit MORE than 80. Actually this is how it is in real life too. When u see 100 on your speedo you actually violate the rule, coz' not even a robot can keep 100.000 kmh it will be a bit more. The only diff between real life and LFS is that in lfs you get penalised for 80.0001, but in real u only get a ticket if u hit the desired speed+10% (here in hungary)

Actually, most cars have optimistic speedometers by 3-5% or more. So, when your speedo shows 100kph you're likely only going about 95kph or so. But, I will agree that if the speedometer was calibrated, and it read 80kph, that you would likely be going 80.001 kph or higher.

I don't think this is a bug at all, and I don't think it should be changed.

In F1 drivers get penalties for being 0.5km/h over the posted limit.

btw: the advantage of going 79 instead of 77 kph could be lost in one turn due to the smallest error, so why even try to drive as fast as possible in pits ?

When your nearest rival is one tenth per lap faster than you, one second saved in the pits is equivalent to ten laps of catching up!

Just a quick example:

You've got a pitlane with an length of 450 meters (which is quite long, but I guess it's about the size of the blackwood pitlane)
Let's say you need about 50 meters (just an example) to brake to stand and to accelerate to your pit speed limit.

These 400 meters of "cruising" at the same speed will take you with

-79 kph: 18.23 seconds
-78 kph: 18.46 seconds
-77 kph: 18.70 seconds

So it might be a half second, but i prefer to drive through the pits safely in order to not get a drive-through

Yeps, GerG is completely right. If you read "80" on your speedo you are actually driving something between 80.000000 and 80.999999 km/h. So if you have no speed limiter, try to stay at 78 km/h as long as 80.000001 is considered as "speeding".

When staying at 78 km/h you can lift the gas a bit when speeding up to 79 so you do not hit the 80.00001+ mark ^_^

Same for mph.
kmh = mph * 1.61
mph = kmh / 1.61

interesting...
i always wondered if i was getting any 'decent' advantage thru my pitstops.
i guess if you are right on the limit (79k/hr) you *can* make up a little time.

Late braking while approaching the pit entry can also be a good way to maximise a stop. There is a risk of course.
