They have been banned in the CBD of my city because they are ridden on footwaths plenty and after numerous collision injuries someone was killed by an electric scooter. They are need to be regulated, licenced and only ridden on the road/cycle paths if they go that fast (whilst also being practically silent mind you).

You came, i came, it was a real mess.

Exactly what i do.

1. pick a grid coordinate and use ctrl+shift with circle selection tool to the size i want.
2. then using the same starting grid coordinate i create a second inner selection but hold down (shift i think?) to do [ - ] selection instead of [ + ] selection and once the negative selection is started press ctrl+shift again to lock it to circle and expand until i have the circle outline i wanted.
