Something was wrong with that polo.When I traveled to Germany in the 80’s I rented a VW Polo that did 135 kph flat out. I quickly learned stay to the right except to pass and watch out for cars in the left lane driving with their left turn signals on. They were moving.
I have done over 160km/h (100mph) with a Polo on a straight road, not much wind.
On M1 motorway here in UK, speed limit is technically 70mph, but there are always road works, so most of it is reduced to 50mph, most of the time!
