It could be a simple explanation. Just because I can run doesn't mean I want to run everywhere I go. I'd rather drive or ride especially if it's a long trip. Plus you never know what could happen so taking a spaceship was probably a wise choice overall. Maybe he was on a long mission that required him to have certain items, tools, etc. that he couldn't just carry.

It's a good thing he had the spaceship actually because after taking the shot to the chest, that escape pod was looking really nice!
