And why that narrow(ness) is important.

 

The larger the volume of the tower,

the more expensive it will be.

 

So preferably, designed specifically

for this type of vehicle.

 

No normal vehicles allowed.

 

(Poses threat to themselves)

 

It must be able to float as I mentioned,

must be able to fly to certain amount of time,

and it would be helpful if it can turn into

a motorcycle. I think a 5-seater, (instead six

from previous) with the last one being

able to stand above the jumbo wheels in height,

to be able to see in clarity.

 

May save energy. (Less weight/less space by 15~20 percent)

 

 

And if no normal vehicles are allowed

in this intercontinental drive,

 

 

it will further promote usage of the flying vehicle.

 

 

While plastic may sound like a cheap replacement

to steel,

 

it is cost-effective for production and economical for the buyer,

and it will have its usage, to be able to float on water

in case of emergencies.

 

And, fortified plastic will not 'break'. Only bend.

Head-on collision will only have two vehicles dismantling

the energy upon impact.
