Its easy to avoid getting scanned, a aggressor starts a scan then just shot at him once and he will stop.I just wanted to try it out.
Highwaking still takes time and I can still get scanned on my way out the door by the pirate which will cause mission failure.
That's the point.
I was given a nonoptional sidequest to deal with pirates who were trying to kill my passenger much like pirates who try to attack you when you're hauling cargo and your contact tells you someone's out to get your cargo. I can't stop them from scanning me and I can ether suffer getting interdicted or I can stop, deal with them, collect an extra reward, and move on.
In short, being scanned if you decide to deal with the problem is unavoidable. Breaking interdiction isn't a problem for me but I wasn't in the mood for running. I'd rather swat the gnat and move on. Which was supposed to be the point of that sidequest. Swat the who thinks they can with you. Get free cash.
Really, just don't take those mission do the other passangers that don't care about being scanned. Spend a couple hours in the Beluga making about 100 mil without ever taking a don't get scanned mission. Just don't take em and let the people who like that gameplay have fun with it, both sides can here have what they want instead of just one side.
