Flashed to speed up today

I’m a seasoned driver (which means I’m old …not necessarily any good)

For the second time this month I’ve been flashed and honked by a driver to speed up when in lane 1!!

Was in flowing traffic doing around 70 but being overtaken by traffic in lane 2 (all fine & normal)

A very animated fellow zoomed up behind me flashing honking and gesturing for me to get out his way …I’m guessing expecting me to either swerve into the hard shoulder or into the side of the car legitimately overtaking me.

I’ve experienced it in lane 4 before when I’m passing someone slower than a maniac wanting to not drive lower than the ton+ he or she is doing, but bemused for it to happen in lane 1.

…Guess they cba to overtake and just want an entire lane to themselves. As they could easily have moved (safely) across two or three lanes to overtake other traffic properly.

…TLDR. Me rambling about the impatience of morons.
