At least they are taking safety measures.
The UCI is doing a bunch of lip service, mostly in French!! Making broad brush changes to handlebar widths is based on one or all of three things, opinion, pseudo science, or no science at all. Where is the data set for anything? 10 tooth cogs are dangerous?
Who is riding @65s? So if you are doing a mostly downhill criterium in a hurricane, disc wheels or 65mm profile likely unstable and dangerous, thanks for the rule change, said nobody, because nobody was doing it!!
Narrow handlebars are likely a factor but not the root cause of crashes. Road and track riders much prefer bumping arms and elbows vs handlebars, just sort of accepted for centuries of racing,
Do narrow bars give riders a feeling like 1 more sardine will fit in the tightly packed bunch? Probably. But it's only certain types of riders that enjoy rubbing arm hair at @60-70k an hour anyway.. And most of them will not be affected by @38-40 because shoulders are close to that width being OK.
Eddy Merckx was 6ft tall and in his day rode 38s..so narrow was a thing back when.
For female riders ,smaller folks, bike fitters, sports medicine specialists, making people ride a bike that doesn't fit isn't safe, it's stupid.
Industry and sport always fragile at best, asking developers and manufacturers to turn on a dime with arbitrary rule changes , that's dangerous, possibly putting people out of business and physically in pain, possible long term or permanent injuries from riding wrong bike, especially at pro volume for training and racing..if you are on your bike @22-35+ hours a week and it's got a funny fitting something is going to go wrong. People who pushed for changes look like a limited bunch.. And rumors are Marc Madiot , was big contributor to opinion.
Need some transparency not mad scientists doing experiments.. Real life has female and smaller racers asking how come? And qualify their questions, with data, personal observation about why riding wrong bar and stem length is a bad thing, no response from UCI, and public kick around, nobody can figure out who the UCI asked about handlebars or cog size before rule changes..
If they called me and asked for science, some real life stuff I know works, 25-30 wheel profile and 32 spoke minimum, tire weight and diameter will slow things down. But instead UCI think aero helmets are a major culprit in safety, not for not protecting riders, but because they make you go too fast!! It's like Peewee Herman advised UCI safety team!!
After listening to dozens of ex pros, recently exited racers, everyone is stronger, better, faster, tactics are faster, races are faster through philosophy.. Teams are racing hard all the time.. There is no slow, relaxed, safe pace anymore..
