This crossroads in Cleveleys might look like an opportunity to briefly increase speed to 30 mph, but only a dragster would be able to hit 30 over such a short distance. And then slowing down might be a problem.

A city traffic engineer credits the success to lower speed limits and smarter design.
Helsinki has not recorded a single traffic fatality in the past 12 months, city and police officials confirmed this week. The city's most recent fatal accident occurred in early July 2024 on Keinulaudantie in the city's Kontula district. Authorities are calling the situation exceptional. "A lot of factors contributed to this, but speed limits are one of the most important," said Roni Utriainen, a traffic engineer with the city's Urban Environment Division. Slower speeds, safer streets According to Utriainen, more than half of Helsinki's streets now have a speed limit of 30 km/h. Fifty years ago, that proportion featured 50 km/h limits. Earlier this summer, Helsinki decided to lower speed limits near schools to 30 km/h, a measure that is set to take effect as the academic year begins.

There's a speed limit sign in Distress Calls which indicates that the speed limit within Ninjago City limits is 50 units. Based on Ninjago's (the cartoon) country of origin, Canada, and the average speed limits in urban areas of Canada, this would mean that the speed limit within Ninjago's city limits is 50 kilometers per hour, or 31 miles per hour (it is worth noting that Denmark, where Lego is based, has the same speed limits). The Ninjargon text on the speed limit sign says "Maximum", which also reflects what Canadian speed limit signs look like:
The Welsh gov: We're a nation of small villages and most have a road or two going through them, roads that are now getting so bad the locals have put up their own signs asking people to slow down. Lets just trial 20mph limit in built up areas and see what effect that has.
Every nutjob in Britain: The gov are Dictators, marxists, socialism, devolution, 20mph shot my dog, f*cked my wife, fire all the politicians, THEY, green conspiracy, 20mph stole all my money, stop wasting money fix the nhs, THEY, petition petition, show them whose really in charge, THEY and/or OTHERS, not like you and me, ignore it drive at 90.
