I think your wrong though because static electricity is high voltage low low current. If it was the other way around then humans would be dropping dead left and right because it only takes 1amp to stop a human heart. Some electronics are more sensitive to sudden voltage spikes then others are.

Humans are an interesting scenario- we don't die from static shocks because humans have a resistance value of between 100-300k, so not much happens with high voltage but low current. Think aluminum chasis though, what's the resistance of that? Considerably less. Similarly, what's the resistance of the electrical pathways leading to the control systems? Still considerably less. Static discharges on this level are not harmful to humans, but can be killer to any integrated circuit because of the low resistances (if resistance was any higher on IC's, they wouldn't be able to do their job).
