The effects of geomagnetic disturbances on electrical systems at the Earth's surface

Notice along with electrical grid, pipelines and train tracks are impacted. This is why there is increasing pipeline fires and train derailments. Due to Tesla and other EVs being electric, this has a higher probability of impacting them due to their high voltage wiring in addition to their 12v. This can even cause ICE vehicles electrical systems to catch fire. However there are devices which can reduce this likelihood.

Affected systems include all those that use electrical conductors: whether for transmission of power or signals or where the conducting properties are incidental to their use such as with pipelines and railway tracks. In power systems geomagnetically induced currents cause partial saturation of power transformers producing transformer heating and distortion of the ac waveform leading to misoperation of relays and other equipment. On pipelines, induced currents may contribute to corrosion but also present a problem with the electrical surveys of the pipe performed to monitor the corrosion prevention systems. Severity of these effects depends on disturbance size, proximity to the auroral zone, and the conductivity structure of the Earth. Also significant are system parameters such as the use of higher resistance coatings on pipelines and the linking of power systems into larger networks.

Its important to read then youd understand that earth conductivity plays a large role as well as location. You can see regional impact of the current CME impact here:

Soil conductivity can pay a significant role so even the above website fails to show the true scope of the problem on a specific location. Sort of like how a Tesla glitches several times, but seemingly randomly, when driving over specific locations. But it gives one an idea how different regions are impacted at different times.
