JB is a thug so I am told
Nah, with a junior hacksaw you would be at it all day, as quick as you can go the stroke is a maximum of approx 12cm, most likely when used rapidly less than 8cm, that's cutting stroke it nothing. The only thing in favour is the typically thinner blade and the fact you don't need as much room.
Good hardened steal, especially circular, with a hacksaw is pretty difficult even to get a groove into before you start the proper cutting. You could need to cut through approximately 75% of it before you had a chance with a decent kick, which you would find difficult to get a good angle on given your sat down on a car seat!
The people who can remove these in seconds/minutes are pro-lock smiths most of the time, the people who can be in your house and beat a 100000 lever lock on your front door quicker than you can with your key. THe mass majority of Fiat stealers aren't up to this.
This is why most car crime currently is smash and grab, modern cars are difficult to steal and a crook lock is a good visual deterent.
WHy? Two identicle cars next to each other, one with a lock, the other without. Which would you chose?
There's not a lack of cars around to nick, they would always choose the easiest.
