Again, poor low speed torque is a function of design. Type A induction motors are designed for full speed operation and have low starting torque. That is because they are designed that way. You can design them for stall torque if you wish, and some IM's are. Or you can design for variable torque.
Stationary use IM's are designed for operation direct from mains, with minimal control gear.
They don't have to be, it's not inherent in the IM.
Beyond already commercialised motors you can have active rotor motors with electronics on the rotor to eliminate slip rings, and quite a few other tricks that have not been needed much in the past for stationary motors.
The referred paper was breathlessly suggesting that electric cars are in trouble without REE's for the motors, that is not even close to true. All the tricks that allow a petrol engine to work, can be used in an EV, and if they are economic for petrol cars they are still going to be economic with an electric motor.
Actually they might be improved. My EV has one major failing (despite its PM motors): It has limited stall torque even with PM motors. It can (and has), get trapped by very steep hills, rocks and bits of wood, despite being a 4wd.
This is caused by a design obsession with direct drive and no gear box. If they had even given it a 2 speed overdrive unit, it would have adequate torque.
