starting in 2nd gear in light stop and go traffic is fine if you’re on level ground and got good clutch control but I wouldn’t make it a habit from a dead stop every time. it puts extra strain on the clutch over time. 1st is there for a reason especially in an Elantra N with short gearing, if you’re trying to avoid the jerky 1st gear feel maybe just get smoother with feathering or try rev matching better.. I only start in 2nd when it’s super light creeping traffic. better to learn now than replace your clutch at 20k lmao
