Not all taxi must not put accessories ... some accessories
useful .
Like Wide Angle rear mirror ? This one a must to see blind spots
la .
Like Sonata must put side blind spots mirror , put one or two ,
no harm .
Some instal air ioniser , well , good for air , why not ?
A simple car stereo with USB , okay lar , for my standard .
But car stereo in taxis not into the extend must put Amplifier ,
extra speakers front & back . This one no need .
Some Ah Peh put extra lighting inside their cab , just in case
see newspaper too dark , count $$$$$$ many cannot see clearly etc
... put extra lighting , ok lar in my opinion .
