Consider your piloting skill in terms of when handling will ever become a problem, realistically, and the fact that you can get +1 Handling for just using AR (SR5 page 201). You can also use Edge to break the limit, so really, the Americar will do nicely in most locations. If you really end up needing a limit of 6 (or more, necessitating Edge) on a frequent basis, you probably need to be a dedicated rigger with control rigs, as those opposed tests/thresholds are going to be hard to hit.
