Filtering by two-wheelers (human or engine powered) is legal in the UK. There is recent case law affirming this.
Also, have to take issue with the the article's claim that the car is amazing, and that before the car it would take "all day" to travel 72 km. Before the car there was the bicycle, and it is within many people's ability, with only a small amount of training, to maintain 15 to 20 km/h on a bicycle on unpaved roads. Which would be just under 5 hours to 3½ hours.
Further, the car's ability to cover distance in reasonable amounts of time is only amazing when relatively few others wish to do so at the same time. When that is not the case, e.g. as is typical for 2 to 5 hours / day in and around major urban areas across many parts of the world, the car's terrible space inefficiency gives an amazing *inability* to make reasonable progress, as everyone sits in pollution spewing traffic jams, with average journey times often lower than they would achieve on a bicycle.
With more and more of us living in urban areas, the personal car becomes ever more impractical.
