I still get left behind at spawn points (assuming my team are all dead and I can't spawn on them). Before I drive off, I always check my minimap for peeps that have possibly just spawned and wait to see where they go before I drive/fly off....
Had a habit of jumping in the first vehicle I see and race to the closest point, until I realized I playing just like the other peeps, so started to look for team mates at spawn that needs a lift and wait for them and joining up with squads that stick together, even though I'm not in their squad(if I end up in a squad with snipers and a rambo. Mind you I still struggle to get playing rambo under control, it always get me killed.
