Ive managed to go two seasons on the beam type blades on my cars, which isn't bad, but my weather is milder than most areas. The very short wipers (used on rear hatch and wagon type wipers) almost always have to be conventional type wiper blades. I think wiper inserts in general will be less common because it takes far more time to replace inserts. Overall, beam blades will result in more profit to the blade mfgs. Btw, check Michelin blade packaging; Michelin just puts their name and packaging on them, they don't make them.
