I don't know how many of you have encounter this. My hdb area installed gantry parking. Once in a while the system will f*ck up and cant detect your IU unit. Its very frustrating especially peak hr when vehicles will just pile up behind u. And Singapore drivers are f*ck up. Wait 5 min in queue,will start horning u. Its not like I doing it on purpose. And did you know even if install gantry, u still need summon aunties, cause of the 10 min exit rule.
