Coming from experience in my line of work....what one complains about these days never seems to add up to what is actually happening.... To be so quick to judge based on age (and I'd be assuming car too) is highly critical of todays youth....I see old people speeding, middle aged people speeding, young people speeding....everyone does it...whether it's 1,2,3,4,5,45 kmh over the speed limit..... I speed....I'll admit it...I go 4 - 6kmh over the limit...just enough to not get caught or charged for speeding....but I do it.... My honest opinion is go talk to them....if you don't want to go down the road of the smartarse letter....try and come to a resolution if you feel hard done by, or they feel like they are being victimised (to whatever extent).... You'll more than likely find they are the type of people who sit and watch tv all night just to find some guy looking at Miranda Kerr online and ring in to Channel 7 and complain.... Nothing helps misery like spreading it around....
