There's different "levels" of vehicle security barriers (see ISO standard IWA14). This one is only rated to 2,500 kg @ 48 kph (90 degree impact) or 7,200 kg @ 3

There's different "levels" of vehicle security barriers (see ISO standard IWA14). This one is only rated to 2,500 kg @ 48 kph (90 degree impact) or 7,200 kg @ 32 kph (90 degree impact). Making it a lightweight/temporary.
That's exactly how the manufacturer sells it too, listing it under "Temporary Security." Boasting that it is lightweight, small to store, quick to deploy, with only four men and no machines required. Great for events or as a short term solution.
If you look at how it is deployed in London, they have it in locations where you'd never be able to get up to high speed due to the layout of the streets/congestion. With hopefully(?) more long term barriers being in the works.
So I don't think it is a significant criticism to say it is a weak VSB. That's exactly the niche it is trying to fulfil, and exactly how it is advertised.
