40% I mentioned was not the incentive, it's their cut from the ride! Say a ride costs $1, their cut is $0.4, that's why drivers hate them. And tipping is not a common thing in Vietnam, I always tip though.
To be fair the scamming is not unique to Grab, happened on all platform but drivers told me BeGroup (the Viet one) bans u from the platform if u scam drivers at 2nd time. Grab doesn't seem to care.
But they are the most popular platform, open the app and you see different promotions daily, I guess their partners also eat the incentive they give riders. That's why drivers still work for them: poor folks and students from nearby cities coming to SG to make end meet while attending college.
Your positions are fine I think, especially those LEAPS, earning is more like lotto. I lost some with INTC today so I get it :D
D Wave's quantum annealing technology also seems to me that they are the closest, 5-7 years, to usefulness for global optimisation of postman-type problems
