Of course, it's not a safe thing to do. Driving a car is not safe. There were 115,333 road deaths in 2020 (a reduction of 15% I think from 2109) so you've got to be really careful with your arguments when citing what's safe and what isn't. Does everyone criticising these protests drive rigidly within the speed limit and have constant regard as to other people's safety when driving a car? You can twist all these issues to suit a way of thinking but the reality is that 'what-ifs' are pointless. What-if stopping the traffic reduced the number of deaths on the M25 yesterday. See, pointless argument but plausible. What if having lockdowns and not driving cars ever again saved 115,333 people. See, pointless argument but plausible.
