okay so people here CLEARLY don't realize the use of a Parking Pole, pay a visit to Tokyo first and then you'll know how useful it is. Parallel parking a Toyota Soarer or a Honda Legend in a street in Tokyo is not like parking your car in Jinnah super or tariq road.
It's highly unlikely you'll be able to park a similar car over there without scratching your bumper. Thus the manufacturers equip the vehicle's passenger side with a parking pole to assist the driver.
Now before you say this is 'shashka' or 'Japanese people dont know how to park', think for a minute why would a manufacturer equip a car with a certain accessory if there was no need or if it was a 'shashka'. These have been around for more than a decade now. Mostly powered and only come up when the pole button is pressed from the cabin.
Do some research before posting.
Here's what a parking pole looks like:

Back in the 80's and 90's when parking sensors weren't around, parking poles were used and yes even Mercedes equipped their cars with these or were offered as an extra accessory in Japan.
Mercedes called it the 'Parking Assist'
