An unauthorised car meet with around 70 vehicles at Cribbs Causeway was allowed to continue after police 'identified no issues'.
The event organised by Bristol Japanese Meet took place at Centaurus Retail Park at Cribbs Causeway on Bank Holiday Monday from 6pm.
Videos posted on YouTube of the event show sport cars leaving the car park when surrounding shops were closed.
It took place despite Avon and Somerset Constabulary warning against such events after officers dispersed around around 300 drivers gathered for a Clifton Down rally on August 23.
On the Bank Holiday meet, a police spokesman said a report was received at 6.22pm and officers attended to find a 'mainly static display of around 70 cars'.
He said: "Officers attended and found a mainly static display of around 70 cars in the car park.
"Officers engaged with those present and identified no issues. Most of the car enthusiasts moved on by 9.30pm.
"The local neighbourhood team continue to offer support to the private landowner to minimise the impact of such unauthorised events on local communities and businesses."
On Bristol Japanese Meet's Facebook page a post after the event said: "Great meet tonight! Thanks to everyone that came out."
A meeting for September has already been scheduled by the group.
Chief constable Andy Marsh has urged people to report unlawful raves, car meets and gatherings.
Gatherings of more than 30 people are still banned under coronavirus restrictions.

Speaking on a Facebook Live last Wednesday, Chief Constable Marsh said: "If you see people setting up or news on the web about a car gathering, a meet, or a music event, tell us.
“We have had a really good response to that and we have mounted an operation every weekend."
After the car meet on the Downs, the force said it was to review the way it responded to the incident, which saw people complain about motorists driving dangerously in the area.
Avon and Somerset Police Inspector Rob Cheeseman said: "We are very proactive to deal with them as best we can."
