I Dont know if those bugs have been reported before
so in the first video if you are holding mac,tec,mp5 and get into the car and you want to turn the sirene on its okay you can driveby with those weapons
If you are holding deagle,sawnoff and enter in the car and you want to turn on sirene then it gonna change to sawnoff or deagle while u driving
the 2nd bug is you get into the mod garage then get out it gonna change the weapon to the molotov
