You only need to disrupt a few junctions, Blackwell tunnel, Brent Cross, The Westway and London would gridlock,
20 years ago an overweight lorry blocked the Blackwall tunnel at about 16:00 and East London was solid till midnight. I’m not sure how satnav/Waze would make this better or worse.
Similar happened a few weeks ago when there was a shower of rain. Took us 3 hrs to get from Poplar to Rotherhithe and the whole area was at a standstill for about 5 hrs.
