I think I only failed a few times stealing the cars, twice was due to the stealing at sea scenario and once was due to a group targeting CEOs with one using a Jet.
A recent bad moment for was me killing one guy who tried to kill me whilst just cruising around and then having him and his buddy snipe me to hell and back, I get clear and then get texted "11-1 GG".
Now I responded with the fair point that 2 on 1 is hardly worth bragging about, he responds with I shouldn't have killed his friend, I responded with he shouldn't have tried doing the same to me.
And then they started coming after me again so I needed an equaliser, to the tank I went and levelled the playing field, 2 mins later text saying "Tank Scrub".
After I eventually got blown up, they came after me yet again with both a Tank AND a Jet, To think a few minutes before that they were saying i'm a scrub for picking a tank and yet there they were, the guy in the Jet even went into passive mode just to go pick up his jet.
I called them a pair of hypocrites and went and did some missions.
Last night with zero constructive motivation in me, I parachuted from the maze bank to the lower CEO skyscraper nearby and set up shop on the rooftop with a heavy sniper and a homing launcher to keep me company.
I figured if i'm gonna wreck someone's business, might as well do it the old fashioned way.
It was also quite the test of the games draw distance as well, people on foot couldn't be seen at its limits, yet they could be when in a car.
This should give you a more visual idea of what my set up was..
With such an overview of the area including the often busy Los Santos Customs, It was quite a therapeutic hour or so's sniping and occasionally shooting down or scaring off passing choppers with the homing launcher.
All in all, couple of choppers shot down, quite a few civilian cars destroyed, many kills including one thinking he was safe in an Insurgent numerous times.
And then I picked up another parachute, jumped off and landed on a lower rooftop and did it again for another half an hour.
