The Scorpion fx is one of my favourite models that HP has on the market. It has been bought, used, and reviewed extensively and is a well-proven tadpole trike that might not be the fastest, but still aerodynamic, comfortable and great for longer trike tours. 

Plus: as it is foldable, it is also great to transport the trike in the trunk of a car. But note that it doesn’t fit into a frunk of a model 3. Doesn’t need to be an SUV, a very large Sedan might work or better a station wagon.
