This requires the crew to wear power armor, which adds to the speeder's overall weight and power usage.
You may argue that wearing armor allow the crew to hop out and fight on foot if their fragile speeder gets popped, but this is clearly not within the scope of the tabletop game.
Neither is fuel usage. What's your point? Fuel sources in
40K, at least as far as the Marines are concerned, are inexhaustible. They have so much power at their disposal that they can throw starships around without having to bother with little things like the laws of physics, and power their tanks and suits of armour for thousands of years off a single 'battery'.
Power usage is so far down on the list of concerns that it's not even worth mentioning.
