I put about 40lb on it this morning getting ready for work and didn’t see any flex. I’m not sure what loads people want to see, but it seems really durable to me.
Visiting an old thread - I am looking at buying an R1S and am now seeing used 2025 Large+ cars. It is kind of annoying (IMO) there's no clear path to pay-to-unlock to a Max. Some of these used cars will be a very good value if that option does appear.
