I think you’re struggling with the concept of humour,
Taken either in or out of context, I can’t see anything remotely humourous about the following:
Here’s a good solution to the problem of slow vehicles. Just pull over for five minutes, hey preston slow car gone.
It could just be me, but there’s a serious lack of anything inherently funny in that sentence (apart from, in an ironic twist perhaps, the lack of logic behind it).
I also feel frustrated behind a slower vehicle, but in the long run it doesn’t make that much difference. The difference between the slowest most congested trip to my parents and a clear run is about 5 minutes out of a 90 min journey.
Perhaps this is because you don’t drive fast enough, so failing to overtake (yet apparently getting very frustrated about others doing so) makes little difference to your journey time…
5 minutes was usually enough to ensure I didn’t meet the slow car again.
Ditto the above point.
I’ve frequently overtaken trucks and cars here in Oz, then some time later stopped at a servo for a break and a drink, only to see the cavalcade I overtook finally start to catch me up as I’m leaving. That means I actually do the trip in much the same time as those going slower who don’t stop, but i’m a lot more refreshed and alert as a result of having driven faster yet taken appropriate breaks.
