Perodua is smart, if all variants have blind spot and RCTA they are not going to have much sales on AV just with the ACC alone. Unless they upgrade the ACC to be smarter with lane centering and stop go, by then perhaps they may offer blind spot and RCTA to lower variant.

Anyhow, if TS budget allows, just go for the AV. Need dark tint just buy Elevo sun shade for it less than RM100.
