Does that have anything to understooding a game mechanics, particulary one related how speed works in a ship?
Yes, but this is a game, not quite realisitc one when it comes to things moving in space, but it likes to pretend in many "realistic" areas.
In end its just a game, and like any other game, there is mechanics - wich works exacly as they are intented.
For thrusters, its easy - anything bellow minimal mass on current thrusters, does not increases speed any further.
Corsair is preety unique on that regard. Given its base mass of 265T, and even while fully A rated, its still needs couple more hundreds of tons, for its biggest thrusters, to even be affected in any way. Usually ships dont have that much leeway for mass, but thats how it is with Corsair, and its oversized thrusters class.
Thats why comparing an game mechanic, to things related IRL, be it other cars, loaded trucks vs unloaded, realistic physics even other ships within same game, its just... pointless?
As for reasons why is capped at 600 m/s... I'd say... balance reasons. Not that it bothers me, imo its fine as it is.
Hmm, ship of choice, prehaps? Or simple preference.
Must be Courier cockpit... I heard that some cmdrs love it so much, that they cannot bear to sit in anything else... but on more serious note:
Point of Exploration Corsair is preety much as for any other ship. Cmdrs can explore in whatever they want to, in any ship they feel like to... and from what I can tell, Corsair does not look blank when it comes to exploration possibilities... in fact, its quite decent in such role.
