Tax payers money put to good use, he should probably stick to delivering the mail.
In many parts of the world it is common to see postmen on motorbikes and scooters and why not, it makes perfect sense. They are quicker and nimbler so they get to more places faster and likely hardly ever get stuck in traffic. They are also much more efficient on gas. But they probably weren't meant to be used as stunt bikes for jumping ramps. Especially if the postman has no clue how to land them.
Although we can't see the ending of this hilariously botched attempt, we probably gather that this guy is going to stick to his day job, putting tax payers money and in-transit mail to better use.
