I don't know if this is the right place to post this, but I think it would be cool if Elite: Dangerous had a StarTrek-like warp system.
You have to slowly increase the speed of the ship in supercruise. The bigger the ship, the slower it goes in supercruise. If a ship tries to go too fast, the hull of the ship will slowly break apart and modules will malfunction.
Also, you can eject the warp core. ejecting the warp core will require you to input a code (eg. ->, ->, <-, ->). The warp core will provide a huge decoy target and you will vanish of all sensors. You can't jump to other systems, but you can still use supercruise (only up to 10c, though). The cost of replacing a warp core is 10,000cr (sidewinder) to 10,000,000cr (anaconda-class).
These are just some of my ideas.
Or alternatively they could leave it like it is, because that seems to work well enough.
