As one gains more experience and learns more about the game, certain limitations (both mechanical and player) become more apparent.
Eventually one learns which situations are more risky than others, how to mitigate certain risks, and how much reward one can get away with given the risks.
Look at your Pod’s stats.
Due to its insanely high agility, it can effectively “instawarp” on command.
Due to the Pod’s relatively small signature radius (see: its sensor footprint is a little smaller than a frigate’s) it takes a little longer for anything to target lock it.
Now look at the High-Sec (1.0 to 0.5 space) and Low-Sec (0.4 to 0.1 space) mechanics. Specifically those surrounding warp drives.
In order to prevent one from warping away, warp disruption needs to be applied to a target.
Since high-sec and low-sec space disallows Area of Effect warp disruption a person needs to be both target locked and have either a Warp Disruptor or Warp Scrambler applied to them to prevent escape.
Now take this information and combine what has been learned about the Pod.
Most seasoned PvPers will select a celestial of some kind (see: planet, moon, etc) if they see they are about to lose a fight (or just outright die) and start spamming the warp button.
This way, once they are in their pod, they warp off to safety.
Short of a bad connection, bad luck, or a particularly crafty (and mean) opponent… it should almost always be possible to escape in a pod and get to safety in both High-sec and Low-sec.
This is why and how people run around with multi-billion ISK implants in their heads.
If they have enough experience, know-how, and tolerance for the occasional ■■■■ up… it is totally worth it to fly around with 25% to 50% bonuses to armor/shields/speed/tanking/etc.
My suggestion is to fly around a bit without any of the super expensive implants for now. Especially if you plan to put yourself in risky situations.
In fact… I would say to throw yourself into the “deep end” for a bit simply to hone your reactions and figure out where your tolerances lie.
maybe you should think differently: “if some people use costly implants and take the risk to loose them, it probably means that these implants provide some advantages. What i am missing? maybe i should try to improve my knwoledge of game mechanisms to understand what are these adavantages and in which situation”
maybe this game is not for you… have you heard about risk/reward concept?
