Having viewed the Trexa Electric Vehicle Platform, I realised there was a potential issue with the system design.

The point of the main chassis pole in the centre of the chassis platform is to store the battery pack, which can be easily removed when the battery pack has perished.

This offers up the issue of acceleration & deceleration during collisions.

The pack could be launched through the ends of the tube due to the forces that turn the battery pack into a projectile.
