As I recall ... they were originally ( Accelerated Composites ) ... a rookie composites company ... so at best they were a rookie composites company taking a shot at changing into a rookie car company.

I personally would have considered taking them seriously if they had stuck to the original small scale production factory that was already setup and producing vehicles.

It still was ... just not as much as it was before the front wheel drive change from the new management.

Track width widening is only a band-aid at best for poor longitudinal CG placement; it does nothing to xfer tire load from back to front.
Band-Aid , agreed.

However ... sense the question was about stability , CG is only one component of stability ... band-aid or not , the wider front two wheels is a valid method to improve stability.

Agreed.

Separate from bad management choices...

The largest area of disappointment for me in the design was in the final weight for a 3 wheeled carbon fiber 2 person car ... 1,800 pounds... I mean come on ... My 3rd party crash tested Aluminum Body Insight is 1,847 ... 47 Lbs ??? that's it?
