Grass overgrown on bank making no visibility for cars

The grass on ilsham valley is getting extremely long on the bank so when you are driving from the direction of Meadfoot beach to turn into Ilsham Marine drive it is impossible to see around the corner for any car. It could be lethal if a cyclist/motorbike gets hit off their bike as a car tries to see if it is clear to turn into the junction. I have stopped accessing ilsham marine drive from that turning but others may not. Please do something before an accident happens.
