&gt; The good news is that there are almost no diesel motorcycles, so we don’t have to bother with NOx emissions. The closing of cities to diesel cars doesn’t affect us.

Interesting stance, considering some places in Asia have completely banned motor scooters long before even considering a ban on cars because two-stroke engines affect air quality so much more than four-strokers... But heeeey, can't have facts get in the way of positive spin, right?

Motorcycles have only escaped close scrutiny so far in Europe because there are simply not enough of them to really cause notice. But if you replaced every car in, say, Paris with a motorcycle, the air quality would go *down*, not up - despite the nominally lower fuel throughput of the whole fleet. (Additionally, noise pollution would go up. Traffic would be a lot less congested, though that's not an advantage exclusive to a combustion engine.)

Electric motorcycles are every bit as necessary as electric cars.
