Big advantage of flying a ship that can warp around cloaked, you can make hasty safe spots out in the middle of nowhere in the system and use those to warp to a gate from an angle probably not covered by an automatic bubble or expected by most using bubbles launched from ships. “Using the f11 key to get the system map to see which (hopefully unexpected) angle to warp to the exit gate”
If it’s a system you will be going through frequently, It might be worth your while to make more and better safespots in the system to warp to / around.
You could make safespots between 151-250km from gates in a system (150km being the minimum distance one can warp to something from), warp to the spot cloaked, and if the gate is clear you can jump it.
You can narrow the beam of your D-scan and check if somebody is at a gate from quite a distance, also.
If you do get caught in a bubble with a blockade runner, your chances of not having your best day are unfortunately fairly high if someone(s) are there. If caught in a bubble often your choice will have to be to slowboat cloaked out of the bubble. Try not to panic and be ready to warp your pod off if your ship gets blown up. A decent, lucky, and / or prepared opponent has a decent chance of uncloaking you if you’re caught by a bubble, and uncloaked is a bad thing for a BR. So your efforts are best put into trying to avoid getting bubbled in the first place.
Be a slippery, paranoid, and aware fish. Warning - getting away from an “impossible” situation and doing the “impossible” / going where players don’t want you to is fun and addicting and you might find yourself doing it intentionally for your entertainment!
