It's a shame that, when Norwegians changed their counting system, the suggestion of using "to-ti" didn't catch on for 20. It would be analogous to saying "twoty" in English.
Same, and they might even have properly adjusted headlights, but as soon as they tilt up (e.g. due to a speed bump), the flashing lights make it look like they are sending me a light signal. Usually takes a few seconds until I realise they just hit a speed bump.
To be fair, people do still occasionally die during marathons.
