The GDPR is there to protect your personal/sensitive data, or data that can personally identify you. If has nothing whatsoever to do with data capture from industrial machinary.
I remain astounded how ignorant some people are of basic GDPR principle: protecting your _personal_ data.
Industrial data capture can produce detailed traces of your travel no different than tracking your mobile phone. Some can capture personal details that adtech often can't because the sensor suites are more diverse and operate in different environments. We just don't use it for that.
How is this not your personal data?
Exploitation of these types of data sources has been demonstrated for 15+ years at this point. Abuse is often impractical for technical reasons but GDPR doesn't give you free pass on collecting personal data just because you aren't using it like personal data.
