Stuff like that happens.
When I built my 48 Plymouth coupe I ran all the battery cables and wires where I thought they would be out of trouble. Then I added inner fender wells to keep the junk out of the engine compartment.
What I didn't know was when the tires were turned to the extreme right, the tire rubbed against the inner fender, and squeezed the + battery cable between the battery box brace and the inner fender. It took over 5 years before it finally broke through the battery cable insulation and shorted out the positive battery cable. The little fire was out as soon as the cable was disconnected, but I got to replace the battery cable, and about 6" of 3 other wires. You can bet the wires were run differently, and secured better.
