    A common discussion of late in Petaluma has been about "ebike" safety. I quote "ebike", because most of the complaints probably come from vehicles that are already illegal to operate on roads, bought by irresponsible parents.

    But as we sit and watch people in big heavy vehicles blow through stop signs and ignore neighborhood speed limits (really, dude, you need to get to 4th gear in a 25MPH zone?), it's good to put into perspective just how car-brained the discourse is.

    A paragraph from the linked article: By contrast, if we consider a compact SUV, the most popular car for purchase in North America (Brazeau 2021), weighing approximately 1,500 kg (Axsen and Bhardwaj 2024) with an average of 1.2 passengers (“EOD23 - Enquête Origine-Destination,” n.d.) weighing 100 kg each (same assumption as e-micromobility), the maximum speed of the car would need to be 7.3 km/h to match the same 3,375 joules considered for the e-micromobility. For a full-size SUV (approximately 2560 kg), the maximum speed would be 5.7 km/h (Hawley 2021).
