It does get going, doesn't it? Vega is a solid-fuel rocket (except for the fourth stage), and those have really high thrust early on.

If it behaves more like a missile than a satellite launcher that's no coincidence: most missiles are also solid-fuel.

Most missiles are not designed to carry people ;-)

Vega isn't designed for people either. It's a small launcher for small satellites--and though its max payload might loft a Mercury capsule, no one is going to build something that small. Moreover, humans aren't well suited to all-solid rockets. They have a rough acceleration profile and poor failure and abort modes.

But that's not rare. Most launchers, liquid or solid or both, aren't designed to carry people. It's easier, for one, because your abort mode can be "blow up and collect the insurance". (Also, they're ultimately derived from ICBMs.)
