Yeah another reason why just seems odd to me by BMW.128*128 pixels!????
That's not an event-bases sensor - this is an event-based sensor!

The resulting 1280 x 720 HD event-based imager is suitable for a much wider range of applications, including surveillance and monitoring, augmented reality, virtual reality, and drones.
Besides the photodiode, each pixel requires circuits to convert the diode’s current into a logarithmic voltage and determine if there’s been an increase or decrease in luminosity. It’s that circuitry that, in the new sensors, is put on a separate chip that sits behind the pixels and is linked to them by a dense array of copper connections. Previously, the light-sensing area made up only 25 percent of the area of the pixel, now it’s 77 percent.
When a pixel detects a change (an event), all that is output is the coordinates of the pixel, the polarity of the change, and a 1-microsecond-resolution time stamp. The imager consumes 32 milliwatts to register 100,000 events per second and ramps up to just 73 milliwatts at 300 million events per second. A system that dynamically compresses the event data allows the chip to sustain a rate of more than 1 billion events per second.
Has to be a reason obviously that only those 3 companies understand.
