The stress optimized designs are certainly weird looking. I've not seen any in practical use, that bicycle part looks like it would be an 'interesting' test.

Of course in an engineering design required strength is calculated, then a safety factor applied, cost and weight are minimized to provide this level of strength.
Light weighting is a big deal in automotive design currently, reducing weight to help meet fuel efficiency standards.
