I was driving my new BMW i4 this morning.
536 horsepower. 0g CO2 emissions.
I approached a major intersection on the Leopoldstraรe.
I needed to turn left.
I checked my mirrors.
I executed the turn flawlessly.
Behind me, a man in a Ford Fiesta leaned on his horn.
He was furious.
He pulled up next to me at the next red light, red-faced, rolling down his window.
"Hey! Are your indicators broken, asshole? You almost caused a crash!"
I rolled down my acoustic glass window silently.
"Sir," I stated calmly. "My vehicle is in perfect working order."
"Then why didn't you signal?" he sputtered.
"Because of the General Data Protection Regulation (GDPR)."
He looked confused. "What?"
I explained.
"My intended direction of travel is Personally Identifiable Information (PII) under Article 4."
"By activating my amber indicator, I am broadcasting my future location data to unverified third parties without your explicit consent to process that data."
"Do you have a Data Processing Agreement with me? Do you have a 'Legitimate Interest' under Article 6(1)(f) to know that I am going to the recycling center?"
"No. You do not."
"Where I am going is none of your business. My trajectory is encrypted."
I rolled up the window. The light turned green.
I left him there, processing the regulatory framework.
