@Extinct architects and automotive engineers I am right there with you. As a bonus I found out why my one O2 sensor is flakey the connector is not good tight fit anymore anymore.

 

The old sensor was covered in oil the cable had been pinched by the dust cover at some point, that thing had a hard go.

 

Oh if we are making list I am going to add the builders to almost every house I have owned (7 of those, finally designed and built one for myself).

Qualified to thrown stones because I am both engineer and licensed residential builder. Lazy engineering/design and building pisses me off.
