@BadMayh3m E-sports drivers have already said they think drs is OP, I watched the full race, but more importantly you're comparing a group of very similarly skilled drivers all driving EQUAL SPEC CARS who only overtook each other in a nose to tail drs line. The issue is the drs effect on cars of significant performance difference. 2nd slowest car getting caught 1+second a lap by a much faster car should not then be able to just grab on to the faster cars drs when they overtake and start lapping at their pace.
If you watch the big youtubers play career mode you'll quickly see they're constantly saying they need drs, need to get "towed along" etc etc.
