A local taxi auntie has successfully broken the sound barrier while navigating a 1998 Toyota Crown through peak-hour traffic.

Mdm Lim, 64, reportedly hit Mach 1 on the Pan Island Expressway while simultaneously diagnosing her passenger's hormonal imbalances.

"Wah lau, your face skin so oily, must be everyday eat fried chicken right?" she shrieked while drifting across five lanes without signalling.

Authorities confirm the vehicle’s propulsion system was fueled entirely by concentrated menopausal rage and herbal ointment.

LTA officers attempted to intercept the vehicle but were immediately intimidated by Mdm Lim’s aggressive floral blouse and jade bracelet.

"You think I scared TP ah? I drive taxi before your father even know how to use condom lah!" she barked at the pursuing siren.

The passenger remains in shock.
