I guess my main point was that in some cases, like in my example, arguably harmless offence can result to relatively high punishment, because personal income doesn't often translate directly to disposable money. Of course irrational speed limits are also to blame. In exreme cases this can result to absurdly high fines, e.g. as a real-world example from Finland, overspeeding at 82 km/h in 60 km/h area have resulted to 34,000 eur fine.
