It's a tiny car,but when you're sitting in it,it feels like you're sitting in a Lazy Boy recliner. VERY comfortable and roomy seats. And the support they provide is amazing.
That reminds me of the old piping specifications. You can't have the inside diameter bigger than the outside diameter otherwise the hole will be outside the pipe.
PIPING SPECIFICATIONS
All pipe is to be made of a long hole, surrounded by metal centered around the hole.
All pipe is to be hollow throughout the entire length.
All pipe is to be of the very best quality, preferably tubular or pipular.
All acid-proof pipe is to be made of acid proof metal.
Outer-diameter of all pipes must exceed the inner-diameter. Otherwise, the hole will be on the outside of the pipe.
All pipe is to be supplied with nothing in the hole so that water, steam, or other stuff can be put inside at a later date.
All pipe is to be supplied without rust, as this can be more readily put on at the jobsites.
All pipe is to be cleaned free of any covering such as mud, tar, barnacles or any form of manure before putting up, otherwise it will make lumps under the paint.
All pipe over 500 feet in length must have the words "Long Pipe" clearly painted on each end so that the fitter will know that it is a long pipe.
All pipe over two miles in length must also have these words painted on the middle so that the fitter will not have to walk the full length of the pipe to determine if it is long pipe or not.
All pipe over six inches in diameter is to have the words "Large Pipe" painted on it, so that the fitter will not use it for small pipe.
All pipe fittings are to be made of the same stuff as the pipe.
All pipe closers are to be open on one end.
No fittings are to be put on pipe unless specified. If you do, straight pipes become crooked pipes.
